After commit b0bea38705, syslogger prints 63 warnings about failing to
close a listen socket at postmaster startup. That's because the
syslogger process forks before the ListenSockets array is initialized,
so ClosePostmasterPorts() calls "close(0)" 64 times. The first call
succeeds, because fd 0 is stdin.
This has been like this since commit 9a86f03b4e in version 13, which
moved the SysLogger_Start() call to before initializing ListenSockets.
We just didn't notice until commit b0bea38705 added the LOG message.

Commit 7b378237aa added a status message to pg_upgrade that is 60
characters wide. Since the MESSAGE_WIDTH macro is currently set to
60, there is no space between this new status message and the "ok"
or "failed" indicator appended when the step completes. To fix
this problem, this commit increases the value of MESSAGE_WIDTH to
62.

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
branches.

The meson build scripts attempt to find files left over from configure
and fail, mentioning that "make maintainer-clean" should be run to remove
these. This seems to have been done for files generated from configure.
pg_config_paths.h is generated during the actual make build, so seems to
have been missed. This would result in compilation using the wrong
pg_config_paths.h file.
Here we just add this file to generated_sources_ac so that meson errors
out if pg_config_paths.h exists.
Likely this wasn't noticed before because make maintainer-clean will
remove pg_config_paths.h, however, people using the MSVC build scripts
are more likely to run into issues and they have to manually remove
these files and pg_config_paths.h wasn't listed as a conflicting file to
remove in the meson log.

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

The main reason for this change is to reduce different ways of executing
tasks, making it easier to use custom compute resources for cfbot. A secondary
benefit is that the tasks seem slightly faster this way, apparently the
increased startup overhead is outweighed by reduced runtime overhead.

Some of the ambuildempty functions used smgrwrite() directly, followed
by smgrimmedsync(). A few small problems with that:
Firstly, one is supposed to use smgrextend() when extending a
relation, not smgrwrite(). It doesn't make much difference in
production builds. smgrextend() updates the relation size cache, so
you miss that, but that's harmless because we never use the cached
relation size of an init fork. But if you compile with
CHECK_WRITE_VS_EXTEND, you get an assertion failure.
Secondly, the smgrwrite() calls were performed before WAL-logging, so
the page image written to disk had 0/0 as the LSN, not the LSN of the
WAL record. That's also harmless in practice, but seems sloppy.
Thirdly, it's better to use the buffer cache, because then you don't
need to smgrimmedsync() the relation to disk, which adds latency.
Bypassing the cache makes sense for bulk operations like index
creation, but not when you're just initializing an empty index.
Creation of unlogged tables is hardly performance bottleneck in any
real world applications, but nevertheless.
Backpatch to v16, but no further. These issues should be harmless in
practice, so better to not rock the boat in older branches.

Attribute missing values might be needed past the lifetime of the tuple
descriptors from which they are extracted. To avoid possibly using
pointers for by-reference values which might thus be left dangling, we
cache a datumCopy'd version of the datum in the TopMemoryContext. Since
we first search for the value this only needs to be done once per
session for any such value.

tweaked by Tom Lane.

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 warm cache case (the latter from ~1m20s to ~5s).
It doesn't seem great to have diverging sources of packages for CI between
branches, so backpatch to 15 (where CI was added).

Commit b91dd9de was concerned with a theoretical problem with our
non-atomic condition variable operations. If you stop sleeping, and
then cancel the sleep in a separate step, you might be signaled in
between, and that could be lost. That doesn't matter for callers of
ConditionVariableBroadcast(), but callers of ConditionVariableSignal()
might be upset if a signal went missing like this.
Commit bc971f4025c interacted badly with that logic, because it doesn't
use ConditionVariableSleep(), which would normally put us back in the
wait list. ConditionVariableCancelSleep() would be confused and think
we'd received an extra signal, and try to forward it to another backend,
resulting in wakeup storms.
New idea: ConditionVariableCancelSleep() can just return true if we've
been signaled. Hypothetical users of ConditionVariableSignal() would
then still have a way to deal with rare lost signals if they are
concerned about that problem.

The new relation extension logic, introduced in 00d1e02be24, could lead to
slowdowns in some scenarios. E.g., when loading narrow rows into a table using
COPY, the caller of RelationGetBufferForTuple() will only request a small
number of pages. Without concurrency, we just extended using pwritev() in that
case. However, if there is *some* concurrency, we switched between extending
by a small number of pages and a larger number of pages, depending on the
number of waiters for the relation extension logic. However, some
filesystems, XFS in particular, do not perform well when switching between
extending files using fallocate() and pwritev().
To avoid that issue, remember the number of prior relation extensions in
BulkInsertState and extend more aggressively if there were prior relation
extensions. That not just avoids the aforementioned slowdown, but also leads
to noticeable performance gains in other situations, primarily due to
extending more aggressively when there is no concurrency. I should have done
it this way from the get go.

The option causes a measurable slowdown. Macos is, by far, the most expensive
platform for CI, therefore it doesn't make sense to run such a test there.
d3b111e3205 used a small segment size for two tasks, one with autoconf, one
with meson. In hindsight that is a bit overkill, it's unlikely that the option
would silently break. Thus don't move the -Dsegsize_blocks=6, just remove
it. I did however change the autoconf test to use 6 instead of 8 blocks, as
long as we allow it, a non-power-of-two test seems like a good idea.
While at it, add a comment explaining why we use a small segment size for CI.
