#7405
Fixes a bug that breaks queries from non-maindbs when
citus.local_hostname is set to a value different than "localhost".
This is a very old bug doesn't cause a problem as long as Citus catalog
is available to FindWorkerNode(). And the catalog is always available
unless we're in non-main database, which might be the case on main but
not on older releases, hence not adding a `DESCRIPTION`. For this
reason, I don't see a reason to backport this.
Maybe we should totally refrain using LOCAL_HOST_NAME in all code-paths,
but not doing that in this PR as the other paths don't seem to be
breaking something that is user-facing.
```c
char *
GetAuthinfo(char *hostname, int32 port, char *user)
{
char *authinfo = NULL;
bool isLoopback = (strncmp(LOCAL_HOST_NAME, hostname, MAX_NODE_LENGTH) == 0 &&
PostPortNumber == port);
if (IsTransactionState())
{
int64 nodeId = WILDCARD_NODE_ID;
/* -1 is a special value for loopback connections (task tracker) */
if (isLoopback)
{
nodeId = LOCALHOST_NODE_ID;
}
else
{
WorkerNode *worker = FindWorkerNode(hostname, port);
if (worker != NULL)
{
nodeId = worker->nodeId;
}
}
authinfo = GetAuthinfoViaCatalog(user, nodeId);
}
return (authinfo != NULL) ? authinfo : "";
}
```
This patch includes the username in the reported error message.
This makes debugging easier when certain commands open connections
as other users than the user that is executing the command.
```
monitora_snapshot=# SELECT citus_move_shard_placement(102030, 'monitora.db-dev-worker-a', 6005, 'monitora.db-dev-worker-a', 6017);
ERROR: connection to the remote node monitora_user@monitora.db-dev-worker-a:6017 failed with the following error: fe_sendauth: no password supplied
Time: 40,198 ms
```
This PR makes the connections to other nodes for
`mark_object_distributed` use the same user as
`execute_command_on_remote_nodes_as_user` so they'll use the same
connection.
DESCRIPTION: Adds comment on database and role propagation.

I noticed while reviewing #7203 that there as no example of executing
sql on a worker for the pytest README. Since this is a pretty common
thing that people want to do, this PR adds that.
Test isolation_update_node fails on some systems with the following error:
```
-s2: WARNING: connection to the remote node non-existent:57637 failed with the following error: could not translate host name "non-existent" to address: Name or service not known
+s2: WARNING: connection to the remote node non-existent:57637 failed with the following error: could not translate host name "non-existent" to address: Temporary failure in name resolution
```
This slightly modifies an already existing [normalization
rule](739c6d26df/src/test/regress/bin/normalize.sed (L217-L218))
to fix it.

Adding upgrade_basic_before_non_mixed.sql file because while
upgrade_basic_after_non_mixed exist, its before variation didn't exist
as we don't have any "before" steps. However, run_test.py assumes that
all "after" files do have a "before" variation as well. So this PR adds
an empty upgrade_basic_before_non_mixed.sql file.
Also, given that we don't have such a version called as 12.1devel
anymore, change it to 12.1.1.
And finally, let CI skip testing flakyness for upgrade tests both
because it's quite hard to get flaky-test-detection job working for
upgrade tests and also because in the end it is not much useful to test
upgrade tests against flakyness.
Running a query from a Citus non-main database that inserts to
pg_dist_object requires a new connection to the main database itself.
This PR adds that connection to the main database.

DESCRIPTION: Adds support for issuing `CREATE`/`DROP` DATABASE commands
from worker nodes
With this commit, we allow issuing CREATE / DROP DATABASE commands from
worker nodes too.
As in #7278, this is not allowed when the coordinator is not added to
metadata because we don't ever sync metadata changes to coordinator
when adding coordinator to the metadata via
`SELECT citus_set_coordinator_host('<hostname>')`, or equivalently, via
`SELECT citus_add_node(<coordinator_node_name>, <coordinator_node_port>, 0)`.
We serialize database management commands by acquiring a Citus specific
advisory lock on the first primary worker node if there are any workers in the
cluster. As opposed to what we've done in https://github.com/citusdata/citus/pull/7278
for role management commands, we try to avoid from running into distributed deadlocks
as much as possible. This is because, while distributed deadlocks that can happen around
role management commands can be detected by Citus, this is not the case for database
management commands because most of them cannot be run inside in a transaction block.
In that case, Citus cannot even detect the distributed deadlock because the command is not
part of a distributed transaction at all, then the command execution might not return the
control back to the user for an indefinite amount of time.
This fixes#7230.
First of all, using HeapTupleHeaderGetDatumLength(heapTuple) is
definetly wrong, it gives a number that's 4 times less than the correct
tuple size (heapTuple.t_len). See
https://github.com/postgres/postgres/blob/REL_16_0/src/include/access/htup_details.h#L455-L456https://github.com/postgres/postgres/blob/REL_16_0/src/include/varatt.h#L279https://github.com/postgres/postgres/blob/REL_16_0/src/include/varatt.h#L225-L226
When I fixed it, the limit_intermediate_size test failed, so I tried to
understand what's going on there. In original commit fd546cf these
queries were supposed to fail. Then in b3af63c three of the queries that
were supposed to fail suddenly worked and tests were changed to pass
without understanding why the output had changed or how to keep test
testing what it had to test. Even comments saying that these queries
should fail were left untouched. Commit message gives no clue about why
exactly test has changed:
> It seems that when we use adaptive executor instead of task tracker,
we
> exceed the intermediate result size less in the test. Therefore
updated
> the tests accordingly.
Then 3fda2c3 also blindly raised the limit for one of the queries to
keep it working:
3fda2c3254 (diff-a9b7b617f9dfd345318cb8987d5897143ca1b723c87b81049bbadd94dcc86570R19)
When in fe3caf3 that HeapTupleHeaderGetDatumLength(heapTuple) call was
finally added, one of those test queries became failing again.
The other two of them now also failing after the fix. I don't understand
how exactly the calculation of "intermediate result size" that is
limited by citus.max_intermediate_result_size had changed through
b3af63c and fe3caf3, but these numbers are now closer to what
they originally were when this limitation was added in
fd546cf. So these queries should fail, like in the original
version of the limit_intermediate_size test.

DESCRIPTION: Adds REASSIGN OWNED BY propagation
This pull request introduces the propagation of the "Reassign owned by"
statement. It accommodates both local and distributed roles for both the
old and new assignments. However, when the old role is a local role, it
undergoes filtering and is not propagated. On the other hand, if the new
role is a local role, the process involves first creating the role on
worker nodes before propagating the "Reassign owned" statement.
DESCRIPTION: Adds database connection limit, rename and set tablespace
propagation
In this PR, below statement propagations are added
alter database <database_name> with allow_connections = <boolean_value>;
alter database <database_name> rename to <database_name2>;
alter database <database_name> set TABLESPACE <table_space_name>

DESCRIPTION: Adds support for 2PC from non-Citus main databases
This PR only adds support for `CREATE USER` queries, other queries need
to be added. But it should be simple because this PR creates the
underlying structure.
Citus main database is the database where the Citus extension is
created. A non-main database is all the other databases that are in the
same node with a Citus main database.
When a `CREATE USER` query is run on a non-main database we:
1. Run `start_management_transaction` on the main database. This
function saves the outer transaction's xid (the non-main database
query's transaction id) and marks the current query as main db command.
2. Run `execute_command_on_remote_nodes_as_user("CREATE USER
<username>", <username to run the command>)` on the main database. This
function creates the users in the rest of the cluster by running the
query on the other nodes. The user on the current node is created by the
query on the outer, non-main db, query to make sure consequent commands
in the same transaction can see this user.
3. Run `mark_object_distributed` on the main database. This function
adds the user to `pg_dist_object` in all of the nodes, including the
current one.
This PR also implements transaction recovery for the queries from
non-main databases.
Allowing GRANT ADMIN to now also be INHERIT or SET in support of psql16
GRANT role_name [, ...] TO role_specification [, ...] [ WITH { ADMIN |
INHERIT | SET } { OPTION | TRUE | FALSE } ] [ GRANTED BY

Fixes: #7148
Related: #7138
See review changes from https://github.com/citusdata/citus/pull/7164
DESCRIPTION: Adds support for propagating `CREATE`/`DROP` database
In this PR, create and drop database support is added.
For CREATE DATABASE:
* "oid" option is not supported
* specifying "strategy" to be different than "wal_log" is not supported
* specifying "template" to be different than "template1" is not
supported
The last two are because those are not saved in `pg_database` and when
activating a node, we cannot assume what parameters were provided when
creating the database.
And "oid" is not supported because whether user specified an arbitrary
oid when creating the database is not saved in pg_database and we want
to avoid from oid collisions that might arise from attempting to use an
auto-assigned oid on workers.
Finally, in case of node activation, GRANTs for the database are also
propagated.

Process toast option in vacuum was introduced in PG14. The failing test
was supposed to be a part of `multi_utilities.sql`, but it was included
in `pg14.sql` to avoid alternative output for PG13. See
ba62c0a148 (diff-ed03478f693155e2fe092e9ad356bf884dc097f554e8d75eff562d52bbcf7a75L255-L272)
for reference.
However, now that we don't support PG13 anymore, we can move this test
to `multi_utilities.sql`. Moving the test, plus inserting data before
running vacuum freeze such that the freeze is more meaningful and not
flaky, fixes the flakiness problem of the test.
We propagate `SECURITY LABEL [for provider] ON ROLE rolename IS
labelname` to the worker nodes.
We also make sure to run the relevant `SecLabelStmt` commands on a
newly added node by looking at roles found in `pg_shseclabel`.
See official docs for explanation on how this command works:
https://www.postgresql.org/docs/current/sql-security-label.html
This command stores the role label in the `pg_shseclabel` catalog table.
This commit also fixes the regex string in
`check_gucs_are_alphabetically_sorted.sh` script such that it escapes
the dot. Previously it was looking for all strings starting with "citus"
instead of "citus." as it should.
To test this feature, I currently make use of a special GUC to control
label provider registration in PG_init when creating the Citus extension.
While investigating replication slots leftovers
in PR https://github.com/citusdata/citus/pull/7338,
I ran into the following refactoring/cleanup
that can be done in our test suite:
- Add separate test to remove non default nodes
- Remove coordinator removal from `add_coordinator` test
Use `remove_coordinator_from_metadata` test where needed
- Don't print nodeids in `multi_multiuser_auth` and
`multi_poolinfo_usage`
tests
- Use `startswith` when checking for isolation or failure tests
- Add some dependencies accordingly in `run_test.py` for running flaky
test schedules
DESCRIPTION: Adds support from issuing role management commands from worker nodes
It's unlikely to get into a distributed deadlock with role commands, we
don't care much about them at the moment.
There were several attempts to reduce the chances of a deadlock but we
didn't any of them merged into main branch yet, see:
#7325#7016#7009
When I run this test in my local, the size of the table after the DELETE
command is around 58785792. Hence, I assume that the diffs suggest that
the Vacuum had no effect. The current solution is to run the VACUUM
command three times instead of once.

The elements in the array passed to `fetch_intermediate_results` are the
same, but in the opposite order than expected.
To fix this flakiness, we can omit the `"SELECT bytes FROM

understandable that the intermediate results have been fetched.
Fix the flaky test that results in following diff by waiting until the
backend that we want to terminate really terminates, until 5secs.

As outlined in the #7306 I created, the reason for this is related to
only having a single connection open to the node. Finding and fixing the
full cause is not trivial, so instead this PR starts working around
this bug by forcing maximum parallelism. Preferably we'd want
this workaround not to be necessary, but that requires
spending time to fix this. For now having a less flaky CI is
good enough.

A negative amount of leaked connectios is obviously not possible. For
some reason there was a connection open when we checked the initial
amount of connections that was closed afterwards. This could be the
from the maintenance daemon or maybe from the previous test that had not
fully closed its connections just yet.
The change in this PR doesnt't actually fix the cause of the negative
connection, but it simply considers it good as well, by changing the
result to zero for negative values.
With this fix we might sometimes miss a leak, because the negative
number can cancel out the leak and still result in a 0. But since the
negative number only occurs sometimes, we'll still find the leak often
enough.
When executing a prepared CALL, which is not pure SQL but available with
some drivers like npgsql and jpgdbc, Citus entered a code path where a
plan is not defined, while trying to increase its cost. Thus SIG11 when
plan is a NULL pointer.
Fix by only increasing plan cost when plan is not null.
However, it is a bit suspicious to get here with a NULL plan and maybe a
better change will be to not call
ShardPlacementForFunctionColocatedWithDistTable() with a NULL plan at
all (in call.c:134)
bug hit with for example:
```
CallableStatement proc = con.prepareCall("{CALL p(?)}");
proc.registerOutParameter(1, java.sql.Types.BIGINT);
proc.setInt(1, -100);
proc.execute();
```
where `p(bigint)` is a distributed "function" and the param the
distribution key (also in a distributed table), see #7242 for details

It's the common problem where we're missing a column in the ORDER BY

question.

multi_cluster_management. It usually fails like this:

+WARNING: waiting for metadata sync timed out

--------------------------

```
This tries to address that by hardening wait_until_metadata_sync. I
believe the reason for this warning is that there is a race condition in
wait_until_metadata_sync. It's possible for the pre-check to fail, then
have the maintenance daemon send a notification. And only then have the
backend start to listen. I tried to fix it in two ways:
1. First run LISTEN, and only then read do the pre-check.
2. If we time out, check again just to make sure that we did not miss
the notification somehow. And don't show a warning if all metadata is
synced after the timeout.
It's hard to know for sure that this fixes it because the test is not
repeatable and I could not reproduce it locally. Let's just hope for the
best.

Reading from table_desc apparantly has an issue that if the schema gets
deleted from one of the items, while it is being read that we get such
an error.
This change fixes that by not running multi_reference_table in parallel
with citus_local_tables_queries anymore.
I just enhanced the existing code to check if the relation is an index
belonging to a distributed table.
If so the shardId is appended to relation (index) name and the *_size
function are executed as before.
There is a change in an extern function:
`extern StringInfo GenerateSizeQueryOnMultiplePlacements(...)`
It's possible to create a new function and deprecate this one later if
compatibility is an issue.
Fixes https://github.com/citusdata/citus/issues/6496.

This change fixes that by not running together with the
foreign_key_to_reference_table test anymore. In passing it also
simplifies dropping of the test its resources.
DESCRIPTION: This change starts a maintenance deamon at the time of
server start if there is a designated main database.
This is the code flow:
1. User designates a main database:
`ALTER SYSTEM SET citus.main_db = "myadmindb";`
2. When postmaster starts, in _PG_Init, citus calls
`InitializeMaintenanceDaemonForMainDb`
This function registers a background worker to run
`CitusMaintenanceDaemonMain `with `databaseOid = 0 `
3. `CitusMaintenanceDaemonMain ` takes some special actions when
databaseOid is 0:
- Gets the citus.main_db value.
- Connects to the citus.main_db
- Now the `MyDatabaseId `is available, creates a hash entry for it.
- Then follows the same control flow as for a regular db,
There was a bug reported for previous versions of Citus where
shard\_size was returning NULL for tables with spaces in them. It works
fine on the main branch though, but I'm still adding a test for this to
the main branch because it seems a good test to have.
When testing rolling Citus upgrades, coordinator should not be upgraded
until we upgrade all the workers.

This was sometimes failing when running locally due to some local shard
still existing due to. This fixes that. We normally silence all
`drop schema cascade` output like this anyway to avoid unnecessary
diffs when modifying a test later on.
DESCRIPTION: Adds support for ALTER DATABASE <db_name> SET .. statement
propagation
SET statements in Postgres has a common structure which is already being
used in Alter Function
statement.
In this PR, I added a util file; citus_setutils and made it usable for
both for
alter database<db_name>set .. and alter function ... set ... statements.
With this PR, below statements will be propagated
```sql
ALTER DATABASE name SET configuration_parameter { TO | = } { value | DEFAULT }
ALTER DATABASE name SET configuration_parameter FROM CURRENT
ALTER DATABASE name RESET configuration_parameter
ALTER DATABASE name RESET ALL
```
Additionally, there was a bug in processing float values in the common
code block.
I fixed this one as well
Previous
```C
case T_Float:
{
appendStringInfo(buf, " %s", strVal(value));
break;
}
```
Now
```C
case T_Float:
{
appendStringInfo(buf, " %s", nodeToString(value));
break;
}
```
DESCRIPTION: Adds ALTER DATABASE WITH ... and REFRESH COLLATION VERSION
support

ALTER DATABASE <database_name> with CONNECTION LIMIT <integer_value>;
ALTER DATABASE <database_name> REFRESH COLLATION VERSION;

We currently don't support propagating these options in Citus
Relevant PG commits:
https://github.com/postgres/postgres/commit/e3ce2dehttps://github.com/postgres/postgres/commit/3d14e17
Limitation:
We also need to take care of generated GRANT statements by dependencies
in attempt to distribute something else. Specifically, this part of the
code in `GenerateGrantRoleStmtsOfRole`:
```
grantRoleStmt->admin_opt = membership->admin_option;
```
In PG16, membership also has `inherit_option` and `set_option` which
need to properly be part of the `grantRoleStmt`. We can skip for now
since #7164 will take care of this soon, and also this is not an
expected use-case.
Add citus_schema_move() that can be used to move tenant tables within a distributed
schema to another node. The function has two variations as simple wrappers around
citus_move_shard_placement() and citus_move_shard_placement_with_nodeid() respectively.
They pick a shard that belongs to the given tenant schema and resolve the source node
that contain the shards under given tenant schema. Hence their signatures are quite
similar to underlying functions:
```sql
-- citus_schema_move(), using target node name and node port
CREATE OR REPLACE FUNCTION pg_catalog.citus_schema_move(
schema_id regnamespace,
target_node_name text,
target_node_port integer,
shard_transfer_mode citus.shard_transfer_mode default 'auto')
RETURNS void
LANGUAGE C STRICT
AS 'MODULE_PATHNAME', $$citus_schema_move$$;
-- citus_schema_move(), using target node id
CREATE OR REPLACE FUNCTION pg_catalog.citus_schema_move(
schema_id regnamespace,
target_node_id integer,
shard_transfer_mode citus.shard_transfer_mode default 'auto')
RETURNS void
LANGUAGE C STRICT
AS 'MODULE_PATHNAME', $$citus_schema_move_with_nodeid$$;
```
Since in PG16, truncate triggers are supported on foreign tables, we add
the citus_truncate_trigger to Citus foreign tables as well, such that the TRUNCATE
command is propagated to the table's single local shard as well.
Note that TRUNCATE command was working for foreign tables even before this
commit: see https://github.com/citusdata/citus/pull/7170#issuecomment-1706240593 for details
This commit also adds tests with user-enabled truncate triggers on Citus foreign tables:
both trigger on the shell table and on its single foreign local shard.
Relevant PG commit:
https://github.com/postgres/postgres/commit/3b00a94
**Problem:**
Previously we always used an outside superuser connection to overcome
permission issues for the current user while propagating dependencies.
That has mainly 2 problems:
1. Visibility issues during dependency propagation, (metadata connection
propagates some objects like a schema, and outside transaction does not
see it and tries to create it again)
2. Security issues (it is preferrable to use current user's connection
instead of extension superuser)
**Solution (high level):**
Now, we try to make a smarter decision on whether should we use an
outside superuser connection or current user's metadata connection. We
prefer using current user's connection if any of the objects, which is
already propagated in the current transaction, is a dependency for a
target object. We do that since we assume if current user has
permissions to create the dependency, then it can most probably
propagate the target as well.
Our assumption is expected to hold most of the times but it can still be
wrong. In those cases, transaction would fail and user should set the
GUC `citus.create_object_propagation` to `deferred` to work around it.
**Solution:**
1. We track all objects propagated in the current transaction (we can
handle subtransactions),
2. We propagate dependencies via the current user's metadata connection
if any dependency is created in the current transaction to address
issues listed above. Otherwise, we still use an outside superuser
connection.
DESCRIPTION: Fixes some object propagation errors seen with transaction
blocks.

For a database that does not create the citus extension by running
` CREATE EXTENSION citus;`
`CitusHasBeenLoaded ` function ends up querying the `pg_extension` table
every time it is invoked. This is not an ideal situation for a such a
database.
The idea in this PR is as follows:
### A new field in MetadataCache.
Add a new variable `extensionCreatedState `of the following type:
```
typedef enum ExtensionCreatedState
{
UNKNOWN = 0,
CREATED = 1,
NOTCREATED = 2,
} ExtensionCreatedState;
```
When the MetadataCache is invalidated, `ExtensionCreatedState` will be
set to UNKNOWN.
### Invalidate MetadataCache when CREATE/DROP/ALTER EXTENSION citus
commands are run.
- Register a callback function, named
`InvalidateDistRelationCacheCallback`, for relcache invalidation during
the shared library initialization for `citus.so`. This callback function
is invoked in all the backends whenever the relcache is invalidated in
one of the backends. (This could be caused many DDLs operations).
- In the cache invalidation callback,`
InvalidateDistRelationCacheCallback`, invalidate `MetadataCache` zeroing
it out.
- In `CitusHasBeenLoaded`, perform the costly citus is loaded check only
if the `MetadataCache` is not valid.
### Downsides
Any relcache invalidation (caused by various DDL operations) will case
Citus MetadataCache to get invalidated. Most of the time it will be
unnecessary. But we rely on that DDL operations on relations will not be
too frequent.
1. Adds an `sql_row` function, for when a query returns a single row
with multiple columns.
2. Include a `notice_handler` for easier debugging
3. Retry dropping replication slots when they are "in use", this is
often an ephemeral state and can cause flaky tests
In PG16, REINDEX DATABASE/SYSTEM name is optional.
We already don't propagate these commands automatically.
Testing here with run_command_on_workers.

When we create a database, it already needs to be manually created in

DESCRIPTION: Presenting citus_pause_node UDF enabling pausing by

transaction is closed.

This is the final commit that adds
PG16 compatibility with Citus's current features.
You can use Citus community with PG16Beta3. This commit:
- Enables PG16 in the configure script.
- Adds PG16 tests to CI using test images that have 16beta3
- Skips wal2json cdc test since wal2json package is not available for PG16 yet
- Fixes an isolation test

This commit is in the series of PG16 compatibility commits.
It adds some outer join checks to the planner,
the new password_required option to the subscription,
and a crash fix related to PGIOAlignedBlock, see below for more details:
- Fix PGIOAlignedBlock Assert crash in PG16

- Pass planner info as argument to make_simple_restrictinfo
Pre PG16 passing plannerInfo to make_simple_restrictinfo
was only needed for placeholder Vars, which is not the case
in this part of the codebase because we are building the
expression from shard intervals which don't have placeholder
vars.
However, PG16 is counting baserels appearing in clause_relids
and is deleting the rels mentioned in plannerinfo->outer_join_rels
Hence directly accessing plannerinfo.
We will crash if we leave it as NULL.
