The current setup assumes that commands for lz4, zstd and gzip always
exist by default if not enforced by a user's environment. However,
vcpkg, as one example, installs libraries but no binaries, so this
default setup to assume that a command should always be present would
cause failures. This commit improves the detection of such external
commands as follows:
* If a ENV value is available, trust the environment/user and use it.
* If a ENV value is not available, check its execution by looking in the
current PATH, by launching a simple "$command --version" (that should be
portable enough).
** On execution failure, ignore ENV{command}.
** On execution success, set ENV{command} = "$command".
Note that this new rule applies to gzip, lz4 and zstd but not tar that
we assume will always exist. Those commands are set up in the
environment only when using bincheck and taptest. The CI includes all
those commands and I have checked that their setup is correct there. I
have also tested this change in a MSVC environment where we have none of
those commands.
While on it, remove the references to lz4 from the documentation and
vcregress.pl in ~v13. --with-lz4 has been added in v14~ so there is no
point to have this information in these older branches.

edc2332 has introduced in vcregress.pl some control on the environment
variables LZ4, TAR and GZIP_PROGRAM to allow any TAP tests to be able
use those commands. This makes the settings more consistent with
src/Makefile.global.in, as the same default gets used for Make and MSVC
builds.
Each parameter can be changed in buildenv.pl, but as a default gets
assigned after loading buldenv.pl, it is not possible to unset any of
these, and using an empty value would not work with "||=" either. As
some environments may not have a compatible command in their PATH (tar
coming from MinGW is an issue, for one), this could break tests without
an exit path to bypass any failing test. This commit changes things so
as the default values for LZ4, TAR and GZIP_PROGRAM are assigned before
loading buildenv.pl, not after. This way, we keep the same amount of
compatibility as a GNU build with the same defaults, and it becomes
possible to unset any of those values.
While on it, this adds some documentation about those three variables in
the section dedicated to the TAP tests for MSVC.

Physical replication always ships WAL segment files to replicas once
they are complete. This is a problem if one WAL record is split across
a segment boundary and the primary server crashes before writing down
the segment with the next portion of the WAL record: WAL writing after
crash recovery would happily resume at the point where the broken record
started, overwriting that record ... but any standby or backup may have
already received a copy of that segment, and they are not rewinding.
This causes standbys to stop following the primary after the latter
crashes:
LOG: invalid contrecord length 7262 at A8/D9FFFBC8
because the standby is still trying to read the continuation record
(contrecord) for the original long WAL record, but it is not there and
it will never be. A workaround is to stop the replica, delete the WAL
file, and restart it -- at which point a fresh copy is brought over from
the primary. But that's pretty labor intensive, and I bet many users
would just give up and re-clone the standby instead.
A fix for this problem was already attempted in commit 515e3d84a0, but
it only addressed the case for the scenario of WAL archiving, so
streaming replication would still be a problem (as well as other things
such as taking a filesystem-level backup while the server is down after
having crashed), and it had performance scalability problems too; so it
had to be reverted.
This commit fixes the problem using an approach suggested by Andres
Freund, whereby the initial portion(s) of the split-up WAL record are
kept, and a special type of WAL record is written where the contrecord
was lost, so that WAL replay in the replica knows to skip the broken
parts. With this approach, we can continue to stream/archive segment
files as soon as they are complete, and replay of the broken records
will proceed across the crash point without a hitch.
Because a new type of WAL record is added, users should be careful to
upgrade standbys first, primaries later. Otherwise they risk the standby
being unable to start if the primary happens to write such a record.
A new TAP test that exercises this is added, but the portability of it
is yet to be seen.
This has been wrong since the introduction of physical replication, so
backpatch all the way back. In stable branches, keep the new
XLogReaderState members at the end of the struct, to avoid an ABI
break.

This changes zic's default output format from "-b fat" to "-b slim".
We were already using "slim" in v13/HEAD, so those branches drop
the explicit -b switch in the Makefiles. Instead, add an explicit
"-b fat" in v12 and before, so that we don't change the output file
format in those branches. (This is perhaps excessively conservative,
but we decided not to do so in a12079109, and I'll stick with that.)
Other non-cosmetic changes are to drop support for zic's long-obsolete
"-y" switch, and to ensure that strftime() does not change errno
unless it fails.
As usual with tzcode changes, back-patch to all supported branches.
Previously we used pg_atomic_write_64_impl inside
pg_atomic_init_u64. That works correctly, but on platforms without
64bit single copy atomicity it could trigger spurious valgrind errors
about uninitialized memory, because we use compare_and_swap for atomic
writes on such platforms.
I previously suppressed one instance of this problem (6c878edc1d),
but as Tom reports that wasn't enough. As the atomic variable cannot
yet be concurrently accessible during initialization, it seems better
to have pg_atomic_init_64_impl set the value directly.

Commit 6f6b99d13 stuck an INFO message into the fast path for
checking partition constraints, for no very good reason except
that it made it easy for the regression tests to verify that
that path was taken. Assorted later patches did likewise,
increasing the unsuppressable-chatter level from ALTER TABLE
even more. This isn't good for the user experience, so let's
drop these messages down to DEBUG1 where they belong. So as
not to have a loss of test coverage, create a TAP test that
runs the relevant queries with client_min_messages = DEBUG1
and greps for the expected messages.
This testing method is a bit brute-force --- in particular,
it duplicates the execution of a fair amount of the core
create_table and alter_table tests. We experimented with
other solutions, but running any significant amount of
standard testing with client_min_messages = DEBUG1 seems
to have a lot of output-stability pitfalls, cf commits
bbb96c370 and 5655565c0. Possibly at some point we'll look
into whether we can reduce the amount of test duplication.

version of OpenSSL, and they lacked logic to detect the version of
OpenSSL a given compilation of Postgres is linking to (currently 1.0.2,

This commit adds more logic to detect the version of OpenSSL used by a

1.1.0 which requires a new set of compilation flags to work properly.

Since extended statistic got introduced in PostgreSQL 10, there was a
single catalog pg_statistic_ext storing both the definitions and built
statistic. That's however problematic when a user is supposed to have
access only to the definitions, but not to user data.
Consider for example pg_dump on a database with RLS enabled - if the
pg_statistic_ext catalog respects RLS (which it should, if it contains
user data), pg_dump would not see any records and the result would not
define any extended statistics. That would be a surprising behavior.
Until now this was not a pressing issue, because the existing types of
extended statistic (functional dependencies and ndistinct coefficients)
do not include any user data directly. This changed with introduction
of MCV lists, which do include most common combinations of values.
The easiest way to fix this is to split the pg_statistic_ext catalog
into two - one for definitions, one for the built statistic values.
The new catalog is called pg_statistic_ext_data, and we're maintaining
a 1:1 relationship with the old catalog - either there are matching
records in both catalogs, or neither of them.

This is useful for testing on, eg, FreeBSD, where you won't get far
without "-I/usr/local/include".
Also, expand the set of blacklisted-for-unportability atomics headers,
based on noting that arch-x86.h fails to compile on an ARM box. The
other ones I'd omitted seem to compile all right on architectures they
don't belong to, but that's surely too shaky to rely on. Let's do
like we did for the src/include/port/ headers, and ignore all except
the variant that's pulled in by the arch-independent header.
Declaring a function "inline" still doesn't work with Windows compilers
(C99? what's that?), unless the macro provided by pg_config.h is
in-scope, which it is not in our ECPG test programs. So the workaround
I tried to use in commit 7640f9312 doesn't work for Windows. Revert
the change in printf_hack.h, and instead just blacklist that file
in cpluspluscheck --- since it's a not-installed test file, we don't
really need to verify its C++ cleanliness anyway.
Formerly, cpluspluscheck was only meant to examine headers that
we thought of as exported --- but its notion of what we export
was well behind the times. Let's just make it check *all* .h
files, except for a well-defined blacklist, instead.
While at it, improve its ability to use a C++ compiler other than g++,
by scraping the CXX setting from Makefile.global and making it possible
to override the warning options used (per suggestion from Andres Freund).
