meson/ninja do not support specifying dependencies via globs (as those make it
significantly more expensive to check the current build state). Instead
targets should emit dependency information when running that then can be
cheaply re-checked during future builds.
To handle xmllint and xsltproc invocations in the docs, add and use a wrapper
that uses --load-trace to collect dependency information.

When scanning for the end of WAL, pg_resetwal has been maintaining its
own internal logic to calculate segment numbers and to parse a WAL
segment name for its timeline and segment number. The code claimed for
example that XLogFromFileName() cannot be used because it lacks the
possibility of specifying a WAL segment size, which is not the case
since fc49e24, that has made the WAL segment size configurable at
initialization time, extending this routine to do so.
Similarly, this switches one segment number calculation to use
XLByteToSeg() rather than the same logic present in xlog_internal.h.
While on it, switch to TimeLineID in pg_resetwal.c for TLI numbers
parsed from segment names, to be more consistent with
XLogFromFileName(). The maths are exactly the same, but the code gets
simplified.

This commit expands the TAP tests of pg_upgrade when running these with
different major versions for the "old" cluster (to-be-upgraded) and the
"new" cluster (upgraded-to), by backporting some of the buildfarm
facilities directory into the script:
- Remove comments from the dump files, avoiding version-dependent
information.
- Remove empty lines from the dump files.
- Use --extra-float-digits=0 in the pg_dump command, when using an "old"
cluster with version equal to or lower than v11.
- Use --wal-segsize and --allow-group-access in initdb only when the
"old" cluster is equal to or higher than v11.
This allows the tests to pass down to v14 with the main regression test
suite, while v9.5~13 still generate some diffs, but these are minimal
compared to what happened before this commit. Much more could be done,
especially around dump differences with function and procedures (these
can also be avoided with direct manipulation of the dumps loaded, for
example, in a way similar to the buildfarm), but at least the basics are
in place now.

Otherwise we don't use LLVM's flags when building llvmjit_wrap.cpp and
llvmjit_inline.cpp. That can cause compile time failures if the C++ compiler
doesn't default to a new enough C++ standards version and link time failures
due to ABI influencing flags like -fno-rtti.
The pre-v15 behavior was to discard all but the last result,
but with the new behavior of printing all results by default,
we will send each such result to the \g file. However,
we're still opening and closing the \g file for each result,
so you lose all but the last result anyway. Move the output-file
state up to ExecQueryAndProcessResults so that we open/close the
\g file only once per command string.
To support this without changing other behavior, we must
adjust PrintQueryResult to have separate FILE * arguments
for query and status output (since status output has never
gone to the \g file). That in turn makes it a good idea
to push the responsibility for fflush'ing output down to
PrintQueryTuples and PrintQueryStatus.
Also fix an infinite loop if COPY IN/OUT is attempted in \watch.
We used to reject that, but that error exit path got broken
somewhere along the line in v15. There seems no real reason
to reject it anyway as the code now stands, so just remove
the error exit and make sure that COPY OUT data goes to the
right place.
Also remove PrintQueryResult's unused is_watch parameter,
and make some other cosmetic cleanups (adjust obsolete
comments, break some overly-long lines).

This reverts commit db0d67db24 and
several follow-on fixes. The idea of making a cost-based choice
of the order of the sorting columns is not fundamentally unsound,
but it requires cost information and data statistics that we don't
really have. For example, relying on procost to distinguish the
relative costs of different sort comparators is pretty pointless
so long as most such comparator functions are labeled with cost 1.0.
Moreover, estimating the number of comparisons done by Quicksort
requires more than just an estimate of the number of distinct values
in the input: you also need some idea of the sizes of the larger
groups, if you want an estimate that's good to better than a factor of
three or so. That's data that's often unknown or not very reliable.
Worse, to arrive at estimates of the number of calls made to the
lower-order-column comparison functions, the code needs to make
estimates of the numbers of distinct values of multiple columns,
which are necessarily even less trustworthy than per-column stats.
Even if all the inputs are perfectly reliable, the cost algorithm
as-implemented cannot offer useful information about how to order
sorting columns beyond the point at which the average group size
is estimated to drop to 1.
Close inspection of the code added by db0d67db2 shows that there
are also multiple small bugs. These could have been fixed, but
there's not much point if we don't trust the estimates to be
accurate in-principle.
Finally, the changes in cost_sort's behavior made for very large
changes (often a factor of 2 or so) in the cost estimates for all
sorting operations, not only those for multi-column GROUP BY.
That naturally changes plan choices in many situations, and there's
precious little evidence to show that the changes are for the better.
Given the above doubts about whether the new estimates are really
trustworthy, it's hard to summon much confidence that these changes
are better on the average.
Since we're hard up against the release deadline for v15, let's
revert these changes for now. We can always try again later.
Note: in v15, I left T_PathKeyInfo in place in nodes.h even though
it's unreferenced. Removing it would be an ABI break, and it seems
a bit late in the release cycle for that.

But I missed a case: when we're extending the relation, VM concerns
were dealt with only in the relatively-less-likely case that we
fail to conditionally lock the otherBuffer. I think I'd believed
that we couldn't need to worry about it if the conditional lock
succeeds, which is true for the target buffer; but the otherBuffer
was unlocked for awhile so its bit might be set anyway. So we need
to do the GetVisibilityMapPins dance, and then also recheck the

have behavior parallel to what 80a05679d installed for PQsslAttribute:
you get OpenSSL's attributes if conn is NULL or is an SSL-encrypted

The point of this is to have sensible connection-dependent behavior

parallel to what PQsslAttribute(NULL, "library") does.

Up to now, the ID values returned by pg_stat_get_backend_idset() and
used by pg_stat_get_backend_activity() and allied functions were just
indexes into a local array of sessions seen by the last stats refresh.
This is problematic for a few reasons. The "ID" of a session can vary
over its existence, which is surprising. Also, while these numbers
often match the "backend ID" used for purposes like temp schema
assignment, that isn't reliably true. We can fairly cheaply switch
things around to make these numbers actually be the sessions' backend
IDs. The added test case illustrates that with this definition, the
temp schema used by a given session can be obtained given its PID.
While here, delete some dead code that guarded against getting
a NULL return from pgstat_fetch_stat_local_beentry(). That can't
happen as long as the caller is careful to pass an in-range array
index, as all the callers are. (This code may not have been dead
