pgbouncer can cause PQbackendPID() to return negative values due to it
filling be_pid with random bytes (even these days pid_max can only be
set up to 2^22 on 64b machines on Linux, for example, so this cannot
happen with normal PID numbers). When this happens, pg_basebackup may
generate a temporary slot name that may not be accepted by the parser,
leading to spurious failures, like:
pg_basebackup: error: could not send replication command
ERROR: replication slot name "pg_basebackup_-1201966863" contains
invalid character
This commit fixes that problem by formatting the result from
PQbackendPID() as an unsigned integer when creating the temporary
replication slot name, so as the invalid character is gone and the
command can be parsed.

Dropping a database while a connection is attempted on it was able to
lead to the presence of valid database entries in shared statistics.
The issue is that MyDatabaseId was getting set too early than it should,
as, if the connection attempted on the dropped database fails when
renamed or dropped, the shutdown callback of the shared statistics would
finish by re-inserting a correct entry related to the database already
dropped.
As analyzed by the bug reporters, this issue could lead to phantom
entries in the database list maintained by the autovacuum launcher
(in rebuild_database_list()) if the database dropped was part of the
database list when it was still valid. After the database was dropped,
it would remain the highest on the list of databases to considered by
the autovacuum worker as things to process. This would prevent
autovacuum jobs to happen on all the other databases still present.
The commit fixes this issue by delaying setting MyDatabaseId until the
database existence has been re-checked with the second scan on
pg_database after getting a shared lock on it, and by switching
pgstat_update_dbstats() so as nothing happens if MyDatabaseId is not
valid.

Revalidation of a plancache entry (after a cache invalidation event)
requires acquiring a snapshot. Normally that is harmless, but not
if the cached statement is one that needs to run without acquiring a
snapshot. We were already aware of that for TransactionStmts,
but for some reason hadn't extrapolated to the other statements that
PlannedStmtRequiresSnapshot() knows mustn't set a snapshot. This can
lead to unexpected failures of commands such as SET TRANSACTION
ISOLATION LEVEL. We can fix it in the same way, by excluding those
command types from revalidation.
However, we can do even better than that: there is no need to
revalidate for any statement type for which parse analysis, rewrite,
and plan steps do nothing interesting, which is nearly all utility
commands. To mechanize this, invent a parser function
stmt_requires_parse_analysis() that tells whether parse analysis does
anything beyond wrapping a CMD_UTILITY Query around the raw parse
tree. If that's what it does, then rewrite and plan will just
skip the Query, so that it is not possible for the same raw parse
tree to produce a different plan tree after cache invalidation.
stmt_requires_parse_analysis() is basically equivalent to the
existing function analyze_requires_snapshot(), except that for
obscure reasons that function omits ReturnStmt and CallStmt.
It is unclear whether those were oversights or intentional.
I have not been able to demonstrate a bug from not acquiring a
snapshot while analyzing these commands, but at best it seems mighty
fragile. It seems safer to acquire a snapshot for parse analysis of
these commands too, which allows making stmt_requires_parse_analysis
and analyze_requires_snapshot equivalent.
In passing this fixes a second bug, which is that ResetPlanCache
would exclude ReturnStmts and CallStmts from revalidation.
That's surely *not* safe, since they contain parsable expressions.
Per bug #18059 from Pavel Kulakov. Back-patch to all supported

Backpatch: 15-, where CI support was added
cirrus-ci will soon restrict the amount of free resources every user gets (as
have many other CI providers). For most users of CI that should not be an
issue. But e.g. for cfbot it will be an issue.
To allow configuring different resources on a per-repository basis, introduce
infrastructure for overriding the task execution environment. Unfortunately
this is not entirely trivial, as yaml anchors have to be defined before their
use, and cirrus-ci only allows injecting additional contents at the end of
.cirrus.yml.
To deal with that, move the definition of the CI tasks to
.cirrus.tasks.yml. The main .cirrus.yml is loaded first, then, if defined, the
file referenced by the REPO_CI_CONFIG_GIT_URL variable, will be added,
followed by the contents of .cirrus.tasks.yml. That allows
REPO_CI_CONFIG_GIT_URL to override the yaml anchors defined in .cirrus.yml.
Unfortunately git's default merge / rebase strategy does not handle copied
files, just renamed ones. To avoid painful rebasing over this change, this
commit just renames .cirrus.yml to .cirrus.tasks.yml, without adding a new
.cirrus.yml. That's done in the followup commit, which moves the relevant
portion of .cirrus.tasks.yml to .cirrus.yml. Until that is done,
REPO_CI_CONFIG_GIT_URL does not fully work.
The subsequent commit adds documentation for how to configure custom compute
resources to src/tools/ci/README

A significant chunk of the time on the macos CI task is spent installing
packages using homebrew. The downloads of the packages are cached, but the
installation needs to happen every time. We can't cache the whole homebrew
installation, because it is too large due to pre-installed packages.
Speed this up by installing packages using macports and caching the
installation as .dmg. That's a lot faster than unpacking a tarball.
In addition, don't install llvm - it wasn't enabled when building, so it's
just a waste of time/space.
This substantially speeds up the mac CI time, both in the cold cache and in

The use of Memoize was already disabled in normal joins when the join
conditions had volatile functions per the code in
match_opclause_to_indexcol(). Ordinarily, the parameterization for the
inner side of a nested loop will be an Index Scan or at least eventually
lead to an index scan (perhaps nested several joins deep). However, for
lateral joins, that's not the case and seq scans can be parameterized
too, so we can't rely on match_opclause_to_indexcol().
Here we explicitly check the parameterization for volatile functions and
don't consider the generation of a Memoize path when such functions
are present.

If MERGE executes an UPDATE action on a table with row-level security,
the code incorrectly applied the WITH CHECK clauses from the target
table's INSERT policies to new rows, instead of the clauses from the

against the target table's SELECT policies, if SELECT permissions were
required (likely to always be the case).
In addition, if MERGE executes a DO NOTHING action for matched rows,
the code incorrectly applied the USING clauses from the target table's
DELETE policies to existing target tuples. These policies were applied
as checks that would throw an error, if they did not pass.
Fix this, so that a MERGE UPDATE action applies the same RLS policies
as a plain UPDATE query with a WHERE clause, and a DO NOTHING action
does not apply any RLS checks (other than adding clauses from SELECT
policies to the join).

Commit e7cb7ee14, which introduced the infrastructure for FDWs and

handling of pseudoconstant quals assigned to replaced joins in

To fix, we could add the support by 1) modifying the ForeignPath and
CustomPath structs to store the list of RestrictInfo nodes to apply to
the join, as in JoinPaths, if they represent foreign and custom scans
replacing a join with a scan, and by 2) modifying create_scan_plan() in
createplan.c to use that list in that case, instead of the
baserestrictinfo list, to get pseudoconstant quals assigned to the join;
but #1 would cause an ABI break. So fix by modifying the infrastructure
to just disallow replacing joins with such quals.

A crash in the middle of a checkpoint with some two-phase state data
already flushed to disk by this checkpoint could cause a follow-up crash
recovery to recover twice the same transaction, once from what has been
found in pg_twophase/ at the beginning of recovery and a second time
when replaying its corresponding record.
This would lead to FATAL failures in the startup process during
recovery, where the same transaction would have a state recovered twice
instead of once:
LOG: recovering prepared transaction 731 from shared memory
LOG: recovering prepared transaction 731 from shared memory
FATAL: lock ExclusiveLock on object 731/0/0 is already held
This issue is fixed by skipping the addition of any 2PC state coming
from a record whose equivalent 2PC state file has already been loaded in
TwoPhaseState at the beginning of recovery by restoreTwoPhaseData(),
which is OK as long as the system has not reached a consistent state.
The timing to get a messed up recovery processing is very racy, and
would very unlikely happen. The thread that has reported the issue has

indisvalid is switched to true for partitioned indexes when all its
partitions have valid indexes when attaching a new partition, up to the
top-most parent if all its leaves are themselves valid when dealing with
multiple layers of partitions.
The copy of the tuple from pg_index used to switch indisvalid to true
came from the relation cache, which is incorrect. Particularly, in the
case reported by Shruthi Gowda, executing a series of commands in a
single transaction would cause the validation of partitioned indexes to
use an incorrect version of a pg_index tuple, as indexes are reloaded
after an invalidation request with RelationReloadIndexInfo(), a much
faster version than a full index cache rebuild. In this case, the
limited information updated in the cache leads to an incorrect version
of the tuple used. One of the symptoms reported was the following

Until now, when DROP DATABASE got interrupted in the wrong moment, the removal
of the pg_database row would also roll back, even though some irreversible
steps have already been taken. E.g. DropDatabaseBuffers() might have thrown
out dirty buffers, or files could have been unlinked. But we continued to
allow connections to such a corrupted database.
To fix this, mark databases invalid with an in-place update, just before
starting to perform irreversible steps. As we can't add a new column in the
back branches, we use pg_database.datconnlimit = -2 for this purpose.
An invalid database cannot be connected to anymore, but can still be
dropped.
Unfortunately we can't easily add output to psql's \l to indicate that some

It is interesting that there are no production reports of this problem. That
