I rephrased the error messages to be more in the style of
option_parse_int(), and also made use of the new "detail" message
facility. I didn't actually use option_parse_int() (which could be
used for -n) because libpgfeutils wasn't used here yet and I wanted to
keep this just to string changes. But it could be done in the future.
The documentation didn't specify the name of the per-user service file
on Windows, and extrapolating from the pattern used for other config
files gave the wrong answer. The fact that it isn't consistent with the
others sure seems like a bug, but it's far too late to change that now;
we'd just penalize people who worked it out in the past. So, simply
document the true state of affairs.
In passing, fix some gratuitous differences between the discussions
of the service file and the password file.

Backpatch to all supported branches. I (tgl) also chose to back-patch
the part of commit ba356a397 that touched libpq.sgml's description of
the service file --- in hindsight, I'm not sure why I didn't do so at
the time, as it includes some fairly essential information.

This is a slight, convenient semantics change from what commit
0f0cfb494004 ("Fix parallel operations that prevent oldest xmin from
advancing") introduced that lets us simplify the coding in the one place
where it is used.
Backpatch to 13. This is related to commit 6fea65508a1a ("Tighten
ComputeXidHorizons' handling of walsenders") rewriting the code site
where this is used, which has not yet been backpatched, but it may well
be in the future.

Commit 923def9a53 and 52e4f0cd47 allowed to specify column lists and row
filters for publication tables. This commit extends the
pg_publication_tables view and pg_get_publication_tables function to
display that information.
This information will be useful to users and we also need this for the
later commit that prohibits combining multiple publications with different
column lists for the same table.

An 'else' clause was misplaced in commit 598ac10be1c2, making zero-rows

We weren't checking the length of the column list in the alias clause of
an XMLTABLE or JSON_TABLE function (a "tablefunc" RTE), and it was
possible to make the server crash by passing an overly long one. Fix it
by throwing an error in that case, like the other places that deal with
alias lists.
In passing, modify the equivalent test used for join RTEs to look like
the other ones, which was different for no apparent reason.
This bug came in when XMLTABLE was born in version 10; backpatch to all
stable versions.

We can use a single line to print all tuple counts that MERGE processed,
for conciseness, and elide those that are zeroes. Non-text formats
report all numbers, as is typical.

A value of 0 is allowed for this option since its creation, that would
map with the default of having no partitions for pgbench_accounts, but
6f164e6 broke that by enforcing an error. This commit restores the

In order to estimate the cache hit ratio of a Memoize node, one of the
inputs we require is the estimated number of times the Memoize node will
be rescanned. The higher this number, the large the cache hit ratio is
likely to become. Unfortunately, the value being passed as the number of
"calls" to the Memoize was incorrectly using the Nested Loop's
outer_path->parent->rows instead of outer_path->rows. This failed to
account for the fact that the outer_path might be parameterized by some
upper-level Nested Loop.
This problem could lead to Memoize plans appearing more favorable than
they might actually be. It could also lead to extended executor startup
times when work_mem values were large due to the planner setting overly
large MemoizePath->est_entries resulting in the Memoize hash table being
initially made much larger than might be required.
Fix this simply by passing outer_path->rows rather than
outer_path->parent->rows. Also, adjust the expected regression test
output for a plan change.

Backpatch-through: 14, where Memoize was introduced
Per BF animal chipmunk: CREATE DATABASE could apparently fail due to an
AV process being in the template database and not quitting fast enough
for the 5 second timeout in CountOtherDBBackends(). The test script had
autovacuum_naptime=1s to encourage more activity and opening of fds, but
that wasn't strictly necessary for this test. Take it out.
Per BF animal skink: there was a 300s timeout for all tests in the
script, but apparently that was not enough under valgrind. Let's use
the standard timeout $PostgreSQL::Test::Utils::timeout_default, but
restart it for each query we run.

I started out with the intention to rename value_type to item_type to
avoid a collision with a typedef name that appears on some platforms.
Along the way, I noticed that the adjacent field "format" was not being
correctly handled by the backend/nodes/ infrastructure functions:
copyfuncs.c erroneously treated it as a scalar, while equalfuncs,
outfuncs, and readfuncs omitted handling it at all. This looks like
it might be cosmetic at the moment because the field is always NULL
after parse analysis; but that's likely a bug in itself, and the code's
certainly not very future-proof. Let's fix it while we can still do so
without forcing an initdb on beta testers.
Further study found a few other inconsistencies in the backend/nodes/
infrastructure for the recently-added JSON node types, so fix those too.
catversion bumped because of potential change in stored rules.

Currently, preloaded libraries are expected to request additional
shared memory and LWLocks in _PG_init(). However, it is not unusal
for such requests to depend on MaxBackends, which won't be
initialized at that time. Such requests could also depend on GUCs
that other modules might change. This introduces a new hook where
modules can safely use MaxBackends and GUCs to request additional
shared memory and LWLocks.
Furthermore, this change restricts requests for shared memory and
LWLocks to this hook. Previously, libraries could make requests
until the size of the main shared memory segment was calculated.
Unlike before, we no longer silently ignore requests received at
invalid times. Instead, we FATAL if someone tries to request
additional shared memory or LWLocks outside of the hook.

pgstat_report_stat() is only supposed to be called outside of transactions. In
5891c7a8ed8 I added a pgstat_report_stat() call into LogicalRepApplyLoop()'s
timeout branch. While not commonly reached inside a transaction, it is
reachable (e.g. due to network bottlenecks or the sender being stalled / slow
for some reason).
To fix, add a !IsTransactionState() check.
No test added because there's no easy way to reproduce this case without
patching the code.

A few places used binary_upgrade_* variables without including the header,
which worked without warnings because the variables are defined in those
places. However that can cause linker complaints with MSVC - except that we
don't see them right now, due to the use of a symbol export file.

Run renumber_oids.pl to move high-numbered OIDs down, as per pre-beta
tasks specified by RELEASE_CHANGES. For reference, the command was
./renumber_oids.pl --first-mapped-oid 8000 --target-oid 6205
The original coding did this in pqDropServerData(), which seems
fairly backwards. Pending commands are more like already-queued
output data, which is dropped in pqDropConnection(). Moving the
operation means that we clear the command queue immediately upon
detecting connection drop, which improves the sanity of subsequent
behavior. In particular this eliminates duplicated error message
text as a consequence of code added in b15f25446, which supposed
that a nonempty command queue must mean the prior operation is
still active.
There might be an argument for backpatching this to v14; but as with
b15f25446, I'm unsure about interactions with 618c16707. For now,
given the lack of complaints about v14's behavior, leave it alone.

This follows in the footsteps of commit 2591ee8ec by removing one more
ill-advised shortcut from planning of GroupingFuncs. It's true that
we don't intend to execute the argument expression(s) at runtime, but
we still have to process any Vars appearing within them, or we risk
failure at setrefs.c time (or more fundamentally, in EXPLAIN trying
to print such an expression). Vars in upper plan nodes have to have
referents in the next plan level, whether we ever execute 'em or not.

Three variables in pqsignal.h (UnBlockSig, BlockSig and StartupBlockSig)
were not marked with PGDLLIMPORT, as they are declared in a way that
prevents mark_pgdllimport.pl to detect them. These variables are
redefined in a style more consistent with the other headers, allowing
the script to find and mark them.
PGDLLIMPORT was missing for __pg_log_level in logging.h, so add it
back. The marking got accidentally removed in 9a374b77, just after its
addition in 8ec5694.
While on it, add a comment in mark_pgdllimport.pl explaining what are
the arguments needed by the script (aka a list of header paths).
