The list of transform objects that a function should use is specified
in CREATE FUNCTION's TRANSFORM clause, and then represented indirectly
in pg_proc.protrftypes. However, ProcedureCreate completely ignored
that for purposes of constructing pg_depend entries, and instead made
the function depend on any transforms that exist for its parameter or
return data types. This is bad in both directions: the function could
be made dependent on a transform it does not actually use, or it
could try to use a transform that's since been dropped. (The latter
scenario would require use of a transform that's not for any of the
parameter or return types, but that seems legit for cases where the
function performs SQL operations internally.)
To fix, pass in the list of transform objects that CreateFunction
identified, and build pg_depend entries from that not from the
parameter/return types. This results in changes in the expected
test outputs in contrib/bool_plperl, which I guess are due to
different ordering of pg_depend entries -- that test case is
surely not exercising either of the problem scenarios.
This fix is not back-patchable as-is: changing the signature of
ProcedureCreate seems too risky in stable branches. We could
do something like making ProcedureCreate a wrapper around
ProcedureCreateExt or so. However, I'm more inclined to do
nothing in the back branches. We had no field complaints up to
now, so the hazards don't seem to be a big issue in practice.
And we couldn't do anything about existing pg_depend entries,
so a back-patched fix would result in a mishmash of dependencies
created according to different rules. That cure could be worse
than the disease, perhaps.
I bumped catversion just to lay down a marker that the expected
contents of pg_depend are a bit different than before.

It seems potentially useful to label our shared libraries with version
information, now that a facility exists for retrieving that. This
patch labels them with the PG_VERSION string. There was some
discussion about using semantic versioning conventions, but that
doesn't seem terribly helpful for modules with no SQL-level presence;
and for those that do have SQL objects, we typically expect them
to support multiple revisions of the SQL definitions, so it'd still
not be very helpful.
I did not label any of src/test/modules/. It seems unnecessary since
we don't install those, and besides there ought to be someplace that
still provides test coverage for the original PG_MODULE_MAGIC macro.

The generated resource files aren't exactly the same ones as the old
buildsystems generate. Previously "InternalName" and "OriginalFileName" were
mostly wrong / not set (despite being required), but that was hard to fix in
at least the make build. Additionally, the meson build falls back to a
"auto-generated" description when not set, and doesn't set it in a few cases -
unlikely that anybody looks at these descriptions in detail.

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.

I chanced to notice that this dumped core due to a faulty Assert.
To add insult to injury, the output has been misformatted since v11.
Obviously we need some regression testing here.

plperl's default handling of bool arguments or results is not terribly
satisfactory, since Perl doesn't consider the string 'f' to be false.
Ideally we'd just fix that, but the backwards-compatibility hazard
would be substantial. Instead, build a TRANSFORM module that can
be optionally applied to provide saner semantics.
Perhaps usefully, this is also about the minimum possible skeletal
example of a plperl transform module; so it might be a better starting
point for user-written transform modules than hstore_plperl or
jsonb_plperl.
