Renaming triggers on partitioned tables had two problems: first,
it did not recurse to renaming the triggers on the partitions; and
second, it failed to prohibit renaming clone triggers. Having triggers
with different names in partitions is pointless, and furthermore pg_dump
would not preserve names for partitions anyway.
Not backpatched -- making the ALTER TRIGGER throw an error in stable
versions might cause problems for existing scripts.

This reverts commit 91d395f, to avoid running those tests on Windows.
The tests are globally stable across all buildfarm members, except
fairywren (crash of pg_receivewal) and bowerdird (SIGBREAK preventing
the buildfarm run to complete). Those errors are rather strange, as
other hosts with very similar characteristics are able to run those
tests without breaking a sweat.
For now, disable those tests on Windows to turn back the buildfarm to
green.

Datum sorts can be significantly faster than tuple sorts, especially when
the data type being sorted is a pass-by-value type. Something in the
region of 50-70% performance improvements appear to be possible.
Just in case there's any confusion; the Datum sort is only used when the
targetlist of the Sort node contains a single column, not when there's a
single column in the sort key and multiple items in the target list.

Commit 2c03216d83 changed XLOG_FPI_FOR_HINT records so that they always
included full-page images even when full_page_writes was disabled. However,
in this setting, they don't need to do that because hint bit updates don't
need to be protected from torn writes.
Therefore, this commit makes XLOG_FPI_FOR_HINT records honor full_page_writes
setting. That is, XLOG_FPI_FOR_HINT records may include no full-page images
if full_page_writes is disabled, and WAL replay of them does nothing.

If an error was raised during our initial attempt to check whether
a successfully-compiled expression is "simple", subsequent calls of
exec_stmt_execsql would suppose that stmt->mod_stmt was already computed
when it had not been. This could lead to assertion failures in debug
builds; in production builds the effect would typically be to act as
if INTO STRICT had been specified even when it had not been. Of course
that only matters if the subsequent attempt to execute the expression
succeeds, so that the problem can only be reached by fixing a failure
in some referenced, inline-able SQL function and then retrying the
calling plpgsql function in the same session.
(There might be even-more-obscure ways to change the expression's
behavior without changing the plpgsql function, but that one seems
like the only one people would be likely to hit in practice.)
The most foolproof way to fix this would be to arrange for
exec_prepare_plan to not set expr->plan until we've finished the
subsidiary simple-expression check. But it seems hard to do that
without creating reference-count leak issues. So settle for documenting
the hazard in a comment and fixing exec_stmt_execsql to test separately
for whether it's computed stmt->mod_stmt. (That adds a test-and-branch
per execution, but hopefully that's negligible in context.) In v11 and
up, also fix exec_stmt_call which had a variant of the same issue.

This is a revert of 6cea447, that disabled those tests temporarily on
Windows due to failures with bowerbird where gzflush() would fail when
executed on a freshly-opened compressed and partial segment. This
problem should be taken care of now thanks to 7fbe0c8, so let's see what
the buildfarm has to say on Windows for those tests.
Discussion: https://postgr.es/m/YPDLz2x3o1aX2wRh@paquier.xyz
The logic handling the opening of new WAL segments was fuzzy when using
--compress if a partial, non-compressed, segment with the same base name
existed in the repository storing those files. In this case, using
--compress would cause the code to first check for the existence and the
size of a non-compressed segment, followed by the opening of a new
compressed, partial, segment. The code was accidentally working
correctly on most platforms as the buildfarm has proved, except
bowerbird where gzflush() could fail in this code path. It is wrong
anyway to take the code path used pre-padding when creating a new
partial, non-compressed, segment, so let's fix it.
Note that this issue exists when users mix successive runs of
pg_receivewal with or without compression, as discovered with the tests
introduced by ffc9dda.
While on it, this refactors the code so as code paths that need to know
about the ".gz" suffix are down from four to one in walmethods.c, easing
a bit the introduction of new compression methods. This addresses a
second issue where log messages generated for an unexpected failure
would not show the compressed segment name involved, which was
confusing, printing instead the name of the non-compressed equivalent.

Per build farm animal prairiedog. Also add O_EXCL while here (there are
a few more standard flags but they're not relevant and likely to be
missing).
Macs don't understand O_DIRECT, but they can disable caching with a
separate fcntl() call. Extend the file opening functions in fd.c to
handle this for us if the caller passes in PG_O_DIRECT.
For now, this affects only WAL data and even then only if you set:
max_wal_senders=0
wal_level=minimal
This is not expected to be very useful on its own, but later proposed
patches will make greater use of direct I/O, and it'll be useful for
testing if developers on Macs can see the effects.

As reported by buildfarm member bowerbird, those tests are unstable on
Windows. The failure produced there points to a problem with gzflush(),
that fails to sync a file freshly-opened, with a gzFile properly
opened. While testing this myself with MSVC, I bumped into a different
error where a file could simply not be opened, so this makes me rather
doubtful that testing this area on Windows is a good idea if this
finishes with random concurrency failures. This requires more
investigation, and keeping this buildfarm member red is not a good thing
in the long-term, so for now this just disables this set of tests on
Windows.

Backpatch-through: v14
As of v14, pg_depend contains almost 7000 "pin" entries recording
the OIDs of built-in objects. This is a fair amount of bloat for
every database, and it adds time to pg_depend lookups as well as
initdb. We can get rid of all of those entries in favor of an OID
range check, i.e. "OIDs below FirstUnpinnedObjectId are pinned".
(template1 and the public schema are exceptions. Those exceptions
are now wired into IsPinnedObject() instead of initdb's code for
filling pg_depend, but it's the same amount of cruft either way.)
The contents of pg_shdepend are modified likewise.

The OpenBSD implementation of gzip considers only files suffixed by "Z",
"gz", "z", "tgz" or "taz" as valid targets, discarding anything else and
making a command using --test exit with an error code of 512 if anything
invalid is found. The test introduced in ffc9dda tested a WAL segment
suffixed as .gz.partial, enough to make the test fail.
Testing only a full segment is fine enough in terms of coverage, so
simplify the code by discarding the .gz.partial segment in this check.
This should be enough to make the test pass with OpenBSD environments.
