Postgres got minor updates on Aug10, this commit starts using the
images with the latest version for our tests, namely 14.9 and 15.4.
Depends on https://github.com/citusdata/the-process/pull/147
For CI images, we needed to regenerate Pipfile.lock, mainly because of an issue
with pyyaml version: https://github.com/yaml/pyyaml/issues/601
We also needed to remove a failing test in subquery_local_tables.sql.
Relevant PG commit:

Issue: https://github.com/citusdata/citus/issues/7119
For joins where consider_join_pushdown is false, we cannot get the
information that we used to get, which prevents doing the distributed planning.
Team already contacted PG committers for this.
Until then, we remove the test from the schedule.

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. It makes some changes
to our tests in order to be compatible with the following in PG16:
- Fix multi_subquery_in_where_reference_clause test
somehow PG got rid of the outer join
(e.g., explain doesn't show outer joins),
hence we can pushdown the subquery.
Changing to users_reference_table
- Fix unqualified column names for views in PG16
Relevant PG commit:

Possible relevant PG commit:

ae89129aa3555c263b8c3ccc4c0f1ef7e46201aa
I removed the where clause and the limit count error was hit again.
With the where clause the query unexpectedly works.
- Fix test outputs
Relevant PG commits:
-- 1349d2790b
-- f4c7c410ee
For multi_explain and multi_complex_count_distinct there were too many places
touched so I just added an alternative test output.
For the other tests I modified the problematic parts.

Relevant PG commit:

a14e75eb0b6a73821e0d66c0d407372ec8376105
That commit made LOCALE parameter apply regardless of the
provider used, and it printed the following notice:
NOTICE: using standard form "und-u-ks-level2" for ICU locale "@colStrength=secondary"
We omit this notice to omit output change between pg versions.

Possible relevant PG commit:

9d3ebba729ebaf5882a92f0f5f662a3312037605
memusage is now around 8.5 MB, whereas it was less than 8MB before.
To avoid differences between PG versions, I changed the test to compare
to less than 9 MB. It still reflects very well the improvement from
28MB.

part 4 7c6b4ce103

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.

PG16 compatibility - Part 4
Check out part 1 42d956888d
part 2 0d503dd5ac
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.
