Tom Lane 0245f8db36 Pre-beta mechanical code beautification.
Run pgindent, pgperltidy, and reformat-dat-files.

This set of diffs is a bit larger than typical.  We've updated to
pg_bsd_indent 2.1.2, which properly indents variable declarations that
have multi-line initialization expressions (the continuation lines are
now indented one tab stop).  We've also updated to perltidy version
20230309 and changed some of its settings, which reduces its desire to
add whitespace to lines to make assignments etc. line up.  Going
forward, that should make for fewer random-seeming changes to existing
code.

Tom Lane b124104e73 Fix Utils.pm's locale-munging so that Perl itself is also affected.
Utils.pm has a BEGIN block that editorializes on the locale-related
environment variables, primarily in order to stabilize the behavior
of child programs.  It turns out that if the calling test script
has already done "use locale", this fails to affect the behavior
of Perl itself, causing locale behavior to be different between
Perl and child programs.  That breaks commit cd82e5c79's attempt
to deal with locale-specific behavior in psql.

To fix, we just need to call setlocale() to redo the calculation
of locale.

Per report from Aleksander Alekseev.  No back-patch for now, since
there are no locale-dependent TAP tests in prior branches, and
I'm not yet convinced that this won't have side-effects of its own.

Stephen Frost 6633cfb216 De-Revert "Add support for Kerberos credential delegation"
This reverts commit 3d03b24c3 (Revert Add support for Kerberos
credential delegation) which was committed on the grounds of concern
about portability, but on further review and discussion, it's clear that
we are better off explicitly requiring MIT Kerberos as that appears to
be the only GSSAPI library currently that's under proper maintenance
and ongoing development.  The API used for storing credentials was added
to MIT Kerberos over a decade ago while for the other libraries which
appear to be mainly based on Heimdal, which exists explicitly to be a
re-implementation of MIT Kerberos, the API never made it to a released
version (even though it was added to the Heimdal git repo over 5 years
ago..).

This post-feature-freeze change was approved by the RMT.

Stephen Frost 3d4fa227bc Add support for Kerberos credential delegation
Support GSSAPI/Kerberos credentials being delegated to the server by a
client.  With this, a user authenticating to PostgreSQL using Kerberos
(GSSAPI) credentials can choose to delegate their credentials to the
PostgreSQL server (which can choose to accept them, or not), allowing
the server to then use those delegated credentials to connect to
another service, such as with postgres_fdw or dblink or theoretically
any other service which is able to be authenticated using Kerberos.

Both postgres_fdw and dblink are changed to allow non-superuser
password-less connections but only when GSSAPI credentials have been
delegated to the server by the client and GSSAPI is used to
authenticate to the remote system.

Daniel Gustafsson 7f5b19817e Support connection load balancing in libpq
This adds support for load balancing connections with libpq using a
connection parameter: load_balance_hosts=<string>. When setting the
param to random, hosts and addresses will be connected to in random
order. This then results in load balancing across these addresses and
hosts when multiple clients or frequent connection setups are used.

The randomization employed performs two levels of shuffling:

  1. The given hosts are randomly shuffled, before resolving them
     one-by-one.
  2. Once a host its addresses get resolved, the returned addresses
     are shuffled, before trying to connect to them one-by-one.

Tom Lane a3b65fb282 Fix AdjustUpgrade.pm's view conversion list for --with-lz4.
Turns out the compression.sql test creates a view that needs
to be adjusted in the wake of 47bb9db75 --- except that without
--with-lz4, it fails to create the view at all, so I'd not
noticed this in testing.

Tom Lane 47bb9db759 Get rid of the "new" and "old" entries in a view's rangetable.
The rule system needs "old" and/or "new" pseudo-RTEs in rule actions
that are ON INSERT/UPDATE/DELETE.  Historically it's put such entries
into the ON SELECT rules of views as well, but those are really quite
vestigial.  The only thing we've used them for is to carry the
view's relid forward to AcquireExecutorLocks (so that we can
re-lock the view to verify it hasn't changed before re-using a plan)
and to carry its relid and permissions data forward to execution-time
permissions checks.  What we can do instead of that is to retain
these fields of the RTE_RELATION RTE for the view even after we
convert it to an RTE_SUBQUERY RTE.  This requires a tiny amount of
extra complication in the planner and AcquireExecutorLocks, but on
the other hand we can get rid of the logic that moves that data from
one place to another.

The principal immediate benefit of doing this, aside from a small
saving in the pg_rewrite data for views, is that these pseudo-RTEs
no longer trigger ruleutils.c's heuristic about qualifying variable
names when the rangetable's length is more than 1.  That results
in quite a number of small simplifications in regression test outputs,
which are all to the good IMO.

Bump catversion because we need to dump a few more fields of
RTE_SUBQUERY RTEs.  While those will always be zeroes anyway in
stored rules (because we'd never populate them until query rewrite)
they are useful for debugging, and it seems like we'd better make
sure to transmit such RTEs accurately in plans sent to parallel
workers.  I don't think the executor actually examines these fields
after startup, but someday it might.

This is a second attempt at committing 1b4d280ea.  The difference
from the first time is that now we can add some filtering rules to
AdjustUpgrade.pm to allow cross-version upgrade testing to pass
despite all the cosmetic changes in CREATE VIEW outputs.

Tom Lane 3a36ca03e4 AdjustUpgrade.pm should zap test_ext_cine, too.
test_extensions' test_ext_cine extension has the same upgrade hazard
as test_ext7: the regression test leaves it in an updated state
from which no downgrade path to default is provided.  This causes
the update_extensions.sql script helpfully provided by pg_upgrade
to fail.  So drop it in cross-version-upgrade testing.

Not entirely sure how come I didn't hit this in testing yesterday;
possibly I'd built the upgrade reference databases with
testmodules-install-check disabled.

Tom Lane 52585f8f07 Create common infrastructure for cross-version upgrade testing.
To test pg_upgrade across major PG versions, we have to be able to
modify or drop any old objects with no-longer-supported properties,
and we have to be able to deal with cosmetic changes in pg_dump output.
Up to now, the buildfarm and pg_upgrade's own test infrastructure had
separate implementations of the former, and we had nothing but very
ad-hoc rules for the latter (including an arbitrary threshold on how
many lines of unchecked diff were okay!).  This patch creates a Perl
module that can be shared by both those use-cases, and adds logic
that deals with pg_dump output diffs in a much more tightly defined
fashion.

This largely supersedes previous efforts in commits 0df9641d3,
9814ff550, and 62be9e4cd, which developed a SQL-script-based solution
for the task of dropping old objects.  There was nothing fundamentally
wrong with that work in itself, but it had no basis for solving the
output-formatting problem.  The most plausible way to deal with
formatting is to build a Perl module that can perform editing on the
dump files; and once we commit to that, it makes more sense for the
same module to also embed the knowledge of what has to be done for
dropping old objects.

Back-patch versions of the helper module as far as 9.2, to
support buildfarm animals that still test that far back.
It's also necessary to back-patch PostgreSQL/Version.pm,
because the new code depends on that.  I fixed up pg_upgrade's
002_pg_upgrade.pl in v15, but did not look into back-patching
it further than that.

Andrew Dunstan 9b4eafcaf4 Prevent port collisions between concurrent TAP tests
Currently there is a race condition where if concurrent TAP tests both
test that they can open a port they will assume that it is free and use
it, causing one of them to fail. To prevent this we record a reservation
using an exclusive lock, and any TAP test that discovers a reservation
checks to see if the reserving process is still alive, and looks for
another free port if it is.

Ports are reserved in a directory set by the environment setting
PG_TEST_PORT_DIR, or if that doesn't exist a subdirectory of the top
build directory as set by meson or Makefile.global, or its own
tmp_check directory.

The prove_check recipe in Makefile.global.in is extended to export
top_builddir to the TAP tests. This was already exported by the
prove_installcheck recipes.

Per complaint from Andres Freund

This will be backpatched in due course after some testing.

Andres Freund e6927270cd meson: Add initial version of meson based build system
Autoconf is showing its age, fewer and fewer contributors know how to wrangle
it. Recursive make has a lot of hard to resolve dependency issues and slow
incremental rebuilds. Our home-grown MSVC build system is hard to maintain for
developers not using Windows and runs tests serially. While these and other
issues could individually be addressed with incremental improvements, together
they seem best addressed by moving to a more modern build system.

After evaluating different build system choices, we chose to use meson, to a
good degree based on the adoption by other open source projects.

We decided that it's more realistic to commit a relatively early version of
the new build system and mature it in tree.

This commit adds an initial version of a meson based build system. It supports
building postgres on at least AIX, FreeBSD, Linux, macOS, NetBSD, OpenBSD,
Solaris and Windows (however only gcc is supported on aix, solaris). For
Windows/MSVC postgres can now be built with ninja (faster, particularly for
incremental builds) and msbuild (supporting the visual studio GUI, but
building slower).

Several aspects (e.g. Windows rc file generation, PGXS compatibility, LLVM
bitcode generation, documentation adjustments) are done in subsequent commits
requiring further review. Other aspects (e.g. not installing test-only
extensions) are not yet addressed.

When building on Windows with msbuild, builds are slower when using a visual
studio version older than 2019, because those versions do not support
MultiToolTask, required by meson for intra-target parallelism.

The plan is to remove the MSVC specific build system in src/tools/msvc soon
after reaching feature parity. However, we're not planning to remove the
autoconf/make build system in the near future. Likely we're going to keep at
least the parts required for PGXS to keep working around until all supported
versions build with meson.

Some initial help for postgres developers is at
https://wiki.postgresql.org/wiki/Meson

The motivation for this is twofold. For one the meson patchset would like to
have more control over the logfiles. For another, the log file location for
tap tests (tmp_check/log) is not symmetric to the log location for
pg_regress/isolation tests (log/).

This commit does not change the default location for log files for tap tests,
as that'd break the buildfarm log collection, it just provides the
infrastructure for doing so.

Andres Freund bb54bf2290 Don't hardcode tmp_check/ as test directory for tap tests
This is motivated by the meson patchset, which wants to put the log / data for
tests in a different place than the autoconf build. Right now log files for
tap tests have to be inside $TESTDIR/tmp_check, whereas log files for
pg_regress/isolationtester are outside of tmp_check. This change doesn't fix
the latter, but is a prerequisite.

The only test that needs adjustment is 010_tab_completion.pl, as it hardcoded
the tmp_check/ directory. Instead create a dedicated directory for the test
files.  It's also a bit cleaner independently, because it doesn't intermingle
the test files with more important things like the log/ directory.

John Naylor 4c1532763a Bump minimum Perl version to 5.14
The oldest vendor-shipped Perl in the buildfarm is 5.14.2, which is
the last version that Debian Wheezy shipped. That OS is EOL, but we
keep it running because there is no other convenient way to test certain
non-mainstream 32-bit platforms. There is no bugfix in the 5.14.2 release
that is required, and yet it's also not the latest minor release --
that would be 5.14.4. To clarify the situation, we have thus arranged the
buildfarm to test 5.14.0. That allows configure scripts and documentation
to state 5.14 without fine print.

The MSVC build didn't check the version, since our previous minimum 5.8.3
was considered too old to check for on Windows. We will need a check for
Windows sometime during the v16 cycle, but that could be rendered moot
by the impending Meson conversion, so it seems safe to just document
the requirement for now.

Michael Paquier b39838889e Add pg_version() to PostgreSQL::Test::Cluster
_pg_version (version number based on PostgreSQL::Version) is a field
private to Cluster.pm but there was no helper routine to retrieve it
from a Cluster's node.  The same is done for install_path, for example,
and the version object becomes handy when writing tests that need
version-specific handling.

Add timestamp and elapsed time decorations to TAP test logs
These apply to traces from Test::More functions such as ok(), is(),
diag() and note(). Output from other sources (e.g. external programs
such a initdb) is not affected. The elapsed time is the time since the
last such trace (or the beginning of the test in the first case). Times
and timestamps are at millisecond precision.

Andres Freund 6f0cf87872 pgstat: remove stats_temp_directory.
With stats now being stored in shared memory, the GUC isn't needed
anymore. However, the pg_stat_tmp directory and PG_STAT_TMP_DIR define are
kept, as pg_stat_statements (and some out-of-core extensions) store data in
it.

Docs will be updated in a subsequent commit, together with the other pending
docs updates due to shared memory stats.

Stephen Frost 39969e2a1e Remove exclusive backup mode
Exclusive-mode backups have been deprecated since 9.6 (when
non-exclusive backups were introduced) due to the issues
they can cause should the system crash while one is running and
generally because non-exclusive provides a much better interface.
Further, exclusive backup mode wasn't really being tested (nor was most
of the related code- like being able to log in just to stop an exclusive
backup and the bits of the state machine related to that) and having to
possibly deal with an exclusive backup and the backup_label file
existing during pg_basebackup, pg_rewind, etc, added other complexities
that we are better off without.

This patch removes the exclusive backup mode, the various special cases
for dealing with it, and greatly simplifies the online backup code and
documentation.

Remove use of perl parent module in Cluster.pm
Commit fb16d2c658 used the old but not quite old enough parent module,
which dates to perl version 5.10.1 as a core module. We still have a
dinosaur or two running older versions of perl, so rather than require
an upgrade in those we simply do in place what parent.pm's import()
would have done for us.

Make PostgreSQL::Test::Cluster compatible with all live branches
We do this via a subclass for any branch older than the minimum known
to be compatible with the main package (currently release 12).

This should be useful for constructing cross-version tests.

In theory this could be extended back any number of versions, with
varying degrees of compatibility.

Robert Haas ad4f2c47de Make PostgreSQL::Test::Cluster::run_log() return a useful value.
Curently, some TAP test that directly call the underlying function
PostgreSQL::Test::Utils::run_log() care about the return value, but
none of those that call it via PostgreSQL::Test::Cluster::run_log() care.
However, I'd like to add a test that will care, so adjust this function
to return whatever it gets back from the underlying function, just as
we do for a number of other functions in this module.

Tom Lane 174877f1e3 Harden TAP tests that intentionally corrupt page checksums.
The previous method for doing that was to write zeroes into a
predetermined set of page locations.  However, there's a roughly
1-in-64K chance that the existing checksum will match by chance,
and yesterday several buildfarm animals started to reproducibly
see that, resulting in test failures because no checksum mismatch
was reported.

Since the checksum includes the page LSN, test success depends on
the length of the installation's WAL history, which is affected by
(at least) the initial catalog contents, the set of locales installed
on the system, and the length of the pathname of the test directory.
Sooner or later we were going to hit a chance match, and today is
that day.

Harden these tests by specifically inverting the checksum field and
leaving all else alone, thereby guaranteeing that the checksum is
incorrect.

In passing, fix places that were using seek() to set up for syswrite(),
a combination that the Perl docs very explicitly warn against.  We've
probably escaped problems because no regular buffered I/O is done on
these filehandles; but if it ever breaks, we wouldn't deserve or get
much sympathy.

Although we've only seen problems in HEAD, now that we recognize the
environmental dependencies it seems like it might be just a matter
of time until someone manages to hit this in back-branch testing.
Hence, back-patch to v11 where we started doing this kind of test.

Noah Misch f2698ea02c Introduce PG_TEST_TIMEOUT_DEFAULT for TAP suite non-elapsing timeouts.
Slow hosts may avoid load-induced, spurious failures by setting
environment variable PG_TEST_TIMEOUT_DEFAULT to some number of seconds
greater than 180.  Developers may see faster failures by setting that
environment variable to some lesser number of seconds.  In tests, write
$PostgreSQL::Test::Utils::timeout_default wherever the convention has
been to write 180.  This change raises the default for some briefer
timeouts.  Back-patch to v10 (all supported versions).
