Adding such commands in the main regression test suite is not a good
approach performance-wise as it impacts all the objects in the
regression database, so this additional coverage is added in the TAP
tests of reindexdb where we already run a few REINDEX commands with
SYSTEM and DATABASE so there is no runtime difference for the test.
This additional coverage checks which relations are rewritten with
relfilenode changes, as of:
- a toast index in user table.
- a toast index in catalog table.
- a catalog index.
- a user index.
This test suite is something I have implemented for a separate patch
that reworks a bit the way we handle these two REINDEX behaviors, but it
has enough value in itself to be in a separate commit. This also makes
easier to follow what actually changes once the REINDEX logic is
reworked (currently, DABATASE rewrites both catalog and user tables, and
SYSTEM works only on catalogs).

This fixes problems on windows when logging collector is used in a service,
failing with:
FATAL: could not redirect stderr: Bad file descriptor
This is triggered by 76e38b37a5. The problem is that STDOUT/STDERR_FILENO
aren't defined on windows, which lead us to use _fileno(stdout) etc, but that
doesn't work if stdout/stderr are closed.

parse.pl and check_rules.pl used "no warnings 'uninitialized'",
which doesn't seem like it measures up to current project standards.
Removing that shows that it was hiding various places that accessed
off the end of an array, which are easily protected by minor logic
adjustments. There's no change in the script results.
While here, improve the Makefile rule that invokes these scripts.
It neglected to depend on check_rules.pl, so that editing that file
didn't result in re-running the check; and it ran check_rules.pl
after building preproc.y, so that if check_rules.pl did fail the
next "make" attempt would just bypass it. check_rules.pl failures
are sufficiently un-heard-of that I don't feel a need to back-patch
this.

In db0a272d12 I used open(our $something, ...), which perlcritic doesn't

This is in preparation for building postgres with meson / ninja.
meson's 'capture' (redirecting stdout to a file) is a bit slower than programs
redirecting output themselves (mostly due to a python wrapper necessary for
windows). That doesn't matter for most things, but errcodes.h is a dependency
of nearly everything, making it a bit faster seem worthwhile.
Medium term it might also be worth avoiding writing errcodes.h if its contents
didn't actually change, to avoid unnecessary recompilations.

I do not [yet] understand how, but my prior commit (089480c077) accidentally
removed the exec bit from configure. I'll try to figure that out later, for
now re-add to unbreak the buildfarm.
Until now postgres built extension libraries with global visibility, i.e.
exporting all symbols. On the one platform where that behavior is not
natively available, namely windows, we emulate it by analyzing the input files
to the shared library and exporting all the symbols therein.
Not exporting all symbols is actually desirable, as it can improve loading
speed, reduces the likelihood of symbol conflicts and can improve intra
extension library function call performance. It also makes the non-windows
builds more similar to windows builds.
Additionally, with meson implementing the export-all-symbols behavior for
windows, turns out to be more verbose than desirable.
This patch adds support for hiding symbols by default and, to counteract that,
explicit symbol visibility annotation for compilers that support
__attribute__((visibility("default"))) and -fvisibility=hidden. That is
expected to be most, if not all, compilers except msvc (for which we already
support explicit symbol export annotations).
Now that extension library symbols are explicitly exported, we don't need to
export all symbols on windows anymore, hence remove that behavior from
src/tools/msvc. The supporting code can't be removed, as we still need to
export all symbols from the main postgres binary.

This is in preparation for defaulting to -fvisibility=hidden in extensions,
instead of exporting all symbols. For that symbols intended to be exported
need to be tagged with PGDLLEXPORT. Most extensions only need to do so for
_PG_init() and functions defined with PG_FUNCTION_INFO_V1. Adding central
declarations avoids each extension having to add PGDLLEXPORT. Any existing
declarations in extensions will continue to work if fmgr.h is included before
them, otherwise compilation for Windows will fail.

Don't consider a constant of regconfig or other reg* types to be
shippable unless it refers to a built-in object, or an object in
an extension that's been marked shippable. Without this
restriction, we're too likely to send a constant that will fail
to parse on the remote server.
For the regconfig type only, consider OIDs up to 16383 to be
"built in", rather than the normal cutoff of 9999. Otherwise
the initdb-created text search configurations will be considered
unshippable, which is unlikely to make anyone happy.
It's possible that this new restriction will de-optimize queries
that were working satisfactorily before. Users can restore any
lost performance by making sure that objects that can be expected
to exist on the remote side are in shippable extensions. However,
that's not a change that people are likely to be happy about having
to make after a minor-release update. Between that consideration
and the lack of field complaints, let's just change this in HEAD.

Some of the test cases added by commit 3a0e38504 are failing
intermittently in CI testing. It looks like, when a connection
attempt fails, it's possible for psql to exit and the test script
to slurp up the postmaster's log file before the connected backend
has managed to write the log entry we're expecting to see.
It's not clear whether that's fixable in any robust way. Pending
more thought, just comment out the log_like checks. The ones in
connect_ok tests should be fine, since surely the log entry should
be emitted before we complete the client auth sequence. I took
out all the ones in connect_fails tests though.

Commit 4518c798 blocks signals for a short region of code, but it
assumed that whatever called it had the signal mask set to UnBlockSig on
entry. That may be true today (or may even not be, in extensions in the
wild), but it would be better not to make that assumption. We should
save-and-restore the caller's signal mask.
The PG_SETMASK() portability macro couldn't be used for that, which is
why it wasn't done before. But... considering that commit a65e0864
established back in 9.6 that supported POSIX systems have sigprocmask(),
and that this is POSIX-only code, there is no reason not to use standard
sigprocmask() directly to achieve that.

Currently, debugging client certificate verification failures is
mostly limited to looking at the TLS alert code on the client side.
For simple deployments, sometimes it's enough to see "sslv3 alert
certificate revoked" and know exactly what needs to be fixed, but if
you add any more complexity (multiple CA layers, misconfigured CA
certificates, etc.), trying to debug what happened based on the TLS
alert alone can be an exercise in frustration.
Luckily, the server has more information about exactly what failed in
the chain, and we already have the requisite callback implemented as a
stub. We fill that in, collect the data, and pass the constructed
error message back to the main code via a static variable. This lets
us add our error details directly to the final "could not accept SSL
connection" log message, as opposed to issuing intermediate LOGs.
It ends up looking like
LOG: connection received: host=localhost port=43112
LOG: could not accept SSL connection: certificate verify failed
DETAIL: Client certificate verification failed at depth 1: unable to get local issuer certificate.
Failed certificate data (unverified): subject "/CN=Test CA for PostgreSQL SSL regression test client certs", serial number 2315134995201656577, issuer "/CN=Test root CA for PostgreSQL SSL regression test suite".
The length of the Subject and Issuer strings is limited to prevent
malicious client certs from spamming the logs. In case the truncation
makes things ambiguous, the certificate's serial number is also
logged.

Teach this script to handle function pointer fields honestly.
Previously they were just silently ignored, but that's not likely to
be a behavior we can accept indefinitely. This mostly entails fixing
it so that a field declaration spanning multiple lines can be parsed,
because we have a bunch of such fields that're laid out that way.
But that's a good improvement in its own right.
With that change and a minor regex adjustment, the only struct it
fails to parse in the node-defining headers is A_Const, because
of the embedded union. The path of least resistance is to move
that union declaration outside the struct.
Having done those things, we can make it error out if it finds
any within-struct syntax it doesn't understand, which seems like
a pretty important property for robustness.
This commit doesn't change the output files at all; it's just in
the way of future-proofing.
