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.

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
fetch_intermediate_results..."` line. From the following logs, it is
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

To fix this we now wait for the metadata to be fully synced to all
nodes at the start of the teardown steps.

It's expected that the replication slot is sometimes not cleaned up if
we don't wait until resource cleanup completes. This PR starts doing
that here.

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