This commit is in the series of PG16 compatibility commits. It fixes
AM dependency and grant's admin option:
- Fix with admin option in grants
grantstmt->admin_opt no longer exists in PG16
instead, grantstmt has a list of options, one of them is admin option.

This commit is in the series of PG16 compatibility commits. It:
- Adds buffer_usage_limit to vacuum and analyze
- Adds process_main, skip_database_stats, only_database_stats to vacuum
Important Note: adding these options is actually required for check-vanilla tests to succeed.
However, in concept, this PR belongs to "PG16 new features",
rather than "PG16 regression tests sanity"

This commit is in the series of PG16 compatibility commits. PG16 introduced a new entry
varnnullingrels to Var, which represents our partkey in pg_dist_partition.
This commit does the necessary changes in Citus to support this.

This commit is in the series of PG16 compatibility commits.
It handles the Permission Info changes in PG16. See below:
The main issue lies in the following entries of PlannedStmt: {
rtable
permInfos
}
Each rtable has an int perminfoindex, and its actual permission info is
obtained through the following:
permInfos[perminfoindex]
We had crashes because perminfoindexes were not updated in the finalized
planned statement after distributed planner hook.
So, basically, everywhere we set a query's or planned statement's rtable
entry, we need to set the rteperminfos/permInfos accordingly.

part 2 0d503dd5ac
part 3 907d72e60d
part 4 7c6b4ce103
This commit is in the series of PG16 compatibility commits. Find the explanation below:
If we allow to adjust partitioning, we get a crash when accessing
amcostestimate of partitioned indexes, because amcostestimate is NULL
for them. The following PG commit is the culprit:
3c569049b7
3c569049b7b502bb4952483d19ce622ff0af5fd6
Previously, partitioned indexes would just be ignored.
Now, they are added in the list. However get_relation_info expects the
tables which have partitioned indexes to have the inh flag set properly.
AdjustPartitioningForDistributedPlanning plays with that flag, hence we
don't get the desired behaviour.
The hook is simply removing all partitioned indexes from the list.

part 3 907d72e60d
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
Relevant PG commit:
faeedbcefd
faeedbcefd40bfdf314e048c425b6d9208896d90
- 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.

Similar to https://github.com/citusdata/citus/pull/7077.
As PG 16+ has changed the join restriction information for certain outer
joins, MERGE is also impacted given that is is also underlying an outer
join.
See #7077 for the details.
PG16 compatibility - Part 2
Part 1 provided successful compilation against pg16beta2.
42d956888d
This PR provides ruleutils changes with pg16beta2 and successful CREATE EXTENSION command.
Note that more changes are needed in order to have successful regression tests.
More commits are coming soon ...
For any_value changes, I referred to this commit
8ef94dc1f5
where we did something similar for PG14 support.
Prior to this commit, the code would skip processing the
errors happened for local commands.
Prior to https://github.com/citusdata/citus/pull/5379, it might
make sense to allow the execution continue. But, as of today,
if a modification fails on any placement, we can safely fail
the execution.
The first commit show the problem in action. The second commit
includes the fix and the test fixes.
Tradionally our planner works in the following order:
router - > pushdown -> repartition -> pull to coordinator
However, for INSERT .. SELECT commands, we did not support "router".
In practice, that is not a big issue, because pushdown planning can
handle router case as well.
However, with PG 16, certain outer joins are converted to JOIN without
any conditions (e.g., JOIN .. ON (true)) and the filters are pushed down
to the tables.
When the filters are pushed down to the tables, router planner can
detect. However, pushdown planner relies on JOIN conditions.
An example query:
```
INSERT INTO agg_events (user_id)
SELECT raw_events_first.user_id
FROM raw_events_first LEFT JOIN raw_events_second
ON raw_events_first.user_id = raw_events_second.user_id
WHERE raw_events_first.user_id = 10;
```
As a side effect of this change, now we can also relax certain
limitation that "pushdown" planner emposes, but not "router". So, with
this PR, we also allow those.
Closes https://github.com/citusdata/citus/pull/6772
DESCRIPTION: Prevents unnecessarily pulling the data into coordinator
for some INSERT .. SELECT queries that target a single-shard group
and the expression originating from the source. If the types are different, Citus uses
different hash functions for the two column types, which might lead to incorrect repartitioning
of the result data
Previously, we only checked whether the relations are colocated, but we
ignore the shard indexes. That causes certain queries still to be
accidentally router. We should enforce colocation checks for both shard
index and table colocation id to make the check restrictive enough.
For example, the following query should not be router, and after this
patch, it won't:
```SQL
SELECT
user_id
FROM
((SELECT user_id FROM raw_events_first WHERE user_id = 15) EXCEPT
(SELECT user_id FROM raw_events_second where user_id = 17)) as foo;
```
DESCRIPTION: Enforce shard level colocation with
citus.enable_non_colocated_router_query_pushdown
This PR provides successful compilation against PG16Beta2. It does some
necessary refactoring to prepare for full support of version 16, in
https://github.com/citusdata/citus/pull/6952 .

Pass NULL context to stringToQualifiedNameList, typeStringToTypeName
The pre-PG16 error behaviour for the following
stringToQualifiedNameList & typeStringToTypeName
was ereport(ERROR, ...)
Now with PG16 we have this context input. We preserve the same behaviour
by passing a NULL context, because of the following:
(copy paste comment from PG16)
If "context" isn't an ErrorSaveContext node, this behaves as
errstart(ERROR, domain), and the errsave() macro ends up acting
exactly like ereport(ERROR, ...).

Index scans in PG16 return empty sets because of extra compatibility
enforcement for `ScanKeyInit` arguments.
Could be one of the relevant PG commits:
c8b2ef05f4
This PR fixes all incompatible `RegProcedure` and `Datum` arguments in
all `ScanKeyInit` functions used throughout the codebase.
Helpful for https://github.com/citusdata/citus/pull/6952
This PR fixes the following:
