The previous minimum was to maintain support for Python 3.5, but we
now require Python 3.6 anyway (commit 45363fca63), so that reason is
obsolete. A small raise to Meson 0.57 allows getting rid of a fair
amount of version conditionals and silences some future-deprecated
warnings.
With the version bump, the following deprecation warnings appeared and
are fixed:
WARNING: Project targets '>=0.57' but uses feature deprecated since '0.55.0': ExternalProgram.path. use ExternalProgram.full_path() instead
WARNING: Project targets '>=0.57' but uses feature deprecated since '0.56.0': meson.build_root. use meson.project_build_root() or meson.global_build_root() instead.
It turns out that meson 0.57.0 and 0.57.1 are buggy for our use, so
the minimum is actually set to 0.57.2. This is specific to this
version series; in the future we won't necessarily need to be this
precise.

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.

This commit addresses some inconsistencies with how the options of some
routines from PostgreSQL/Test/ are written, mainly for init() and
init_from_backup() in Cluster.pm. These are written as unquoted, except
in the locations updated here.

This commit reshapes the grammar of some commands to apply a more
consistent style across the board, following rules similar to
ce1b0f9da03e:
- Elimination of some pointless used-once variables.
- Use of long options, to self-document better the options used.
- Use of fat commas to link option names and their assigned values,
including redirections, so as perltidy can be tricked to put them
together.

This commit rewrites a good chunk of the command arrays in TAP tests
with a grammar based on the following rules:
- Fat commas are used between option names and their values, making it
clear to both humans and perltidy that values and names are bound
together. This is particularly useful for the readability of multi-line
command arrays, and there are plenty of them in the TAP tests. Most of
the test code is updated to use this style. Some commands used
parenthesis to show the link, or attached values and options in a single
string. These are updated to use fat commas instead.
- Option names are switched to use their long names, making them more
self-documented. Based on a suggestion by Andrew Dunstan.
- Add some trailing commas after the last item in multi-line arrays,
which is a common perl style.
Not all the places are taken care of, but this covers a very good chunk
of them.

There are a lot of Perl scripts in the tree, mostly code generation
and TAP tests. Occasionally, these scripts produce warnings. These
are probably always mistakes on the developer side (true positives).
Typical examples are warnings from genbki.pl or related when you make
a mess in the catalog files during development, or warnings from tests
when they massage a config file that looks different on different
hosts, or mistakes during merges (e.g., duplicate subroutine
definitions), or just mistakes that weren't noticed because there is a
lot of output in a verbose build.
This changes all warnings into fatal errors, by replacing
use warnings;
by
use warnings FATAL => 'all';
in all Perl files.

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.

There are a number of places where a shell command is constructed with
percent-placeholders (like %x). It's cumbersome to have to open-code
this several times. This factors out this logic into a separate
function. This also allows us to ensure consistency for and document
some subtle behaviors, such as what to do with unrecognized
placeholders.
The unified handling is now that incorrect and unknown placeholders
are an error, where previously in most cases they were skipped or
ignored. This affects the following settings:
- archive_cleanup_command
- archive_command
- recovery_end_command
- restore_command
- ssl_passphrase_command
The following settings are part of this refactoring but already had
stricter error handling and should be unchanged in their behavior:
- basebackup_to_shell.command

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.

Backpatch: 15-, where the test was added in 027fa0fd72
As a demonstration of the sort of thing that can be done by adding a
custom backup target, this defines a 'shell' target which executes a
command defined by the system administrator. The command is executed
once for each tar archive generate by the backup and once for the
backup manifest, if any. Each time the command is executed, it
receives the contents of th file for which it is executed via standard
input.
The configured command can use %f to refer to the name of the archive
(e.g. base.tar, $TABLESPACE_OID.tar, backup_manifest) and %d to refer
to the target detail (pg_basebackup --target shell:DETAIL). A target
detail is required if %d appears in the configured command and
forbidden if it does not.
Patch by me, reviewed by Abhijit Menon-Sen.
