This is in preparation for building postgres with meson / ninja.
We already have duplicated code for this between the make and msvc
builds. Adding a third copy seems like a bad plan, thus move the generation
into a perl script.
As we don't want to rely on perl being available for builds from tarballs,
generate the file during distprep.

Commit db7d1a7b05 missed a couple of places that needed adjustment now
we are not building pgcrypto when openssl is not configured, causing
contrib installcheck to fail in such a case.
The internals of the frontend-side callbacks for SASL are visible in
libpq-int.h, but the header was not getting installed. This would cause
compilation failures for applications playing with the internals of
libpq.

Also "make reformat-dat-files".
The only change worthy of note is that pgindent messed up the formatting
of launcher.c's struct LogicalRepWorkerId, which led me to notice that
that struct wasn't used at all anymore, so I just took it out.
This changes zic's default output format from "-b fat" to "-b slim".
We were already using "slim" in v13/HEAD, so those branches drop
the explicit -b switch in the Makefiles. Instead, add an explicit
"-b fat" in v12 and before, so that we don't change the output file
format in those branches. (This is perhaps excessively conservative,
but we decided not to do so in a12079109, and I'll stick with that.)
Other non-cosmetic changes are to drop support for zic's long-obsolete
"-y" switch, and to ensure that strftime() does not change errno
unless it fails.
As usual with tzcode changes, back-patch to all supported branches.
The IANA tzcode library has a feature to read a time zone file named
"posixrules" and apply the daylight-savings transition dates and times
therein, when it is given a POSIX-style time zone specification that
lacks an explicit transition rule. However, there's a problem with
that code: it doesn't work for dates past the Y2038 time_t rollover.
(Effectively, all times beyond that point are treated as standard
time.) The IANA crew regard this feature as legacy, so their plan is
to remove it not fix it. The time frame in which that will happen
is unclear, but presumably it'll happen well before 2038.
Moreover, effective with the next IANA data update (probably this
fall), the recommended default will be to not install a "posixrules"
file in the first place. The time frame in which tzdata packagers
might adopt that suggestion is likewise unclear, but at least some
platforms will probably do it in the next year or so. While we could
ignore that recommendation so far as PG-supplied tzdata trees are
concerned, builds using --with-system-tzdata will be subject to
whatever the platform's tzdata packager decides to do.
Thus, whether or not we do anything, some increasing fraction of
Postgres users will be exposed to the behavior observed when there
is no "posixrules" file; and if we do nothing, we'll have essentially
no control over the timing of that change.
The best thing to do to ameliorate the uncertainty seems to be to
proactively remove the posixrules-reading feature. If we do that in
a scheduled release then at least we can release-note the behavioral
change, rather than having users be surprised by it after a routine
tzdata update.
The change in question is fairly minor anyway: to be affected,
you have to be using a POSIX-style timezone spec, it has to not
have an explicit rule, and it has to not be one of the four traditional
continental-USA zone names (EST5EDT, CST6CDT, MST7MDT, or PST8PDT),
as those are special-cased. Since the default "posixrules" file
provides USA DST rules, the number of people who are likely to find
such a zone spec useful is probably quite small. Moreover, the
fallback behavior with no explicit rule and no "posixrules" file is to
apply current USA rules, so the only thing that really breaks is the
DST transitions in years before 2007 (and you get the countervailing
fix that transitions after 2038 will be applied).
Now, some installations might have replaced the "posixrules" file,
allowing e.g. EU rules to be applied to a POSIX-style timezone spec.
That won't work anymore. But it's not exactly clear why this solution
would be preferable to using a regular named zone. In any case, given
the Y2038 issue, we need to be pushing users to stop depending on this.
Back-patch into v13; it hasn't been released yet, so it seems OK to
change its behavior. (Personally I think we ought to back-patch
further, but I've been outvoted.)

When installing binaries and libraries using the MSVC installation
routines, the operation gets done after moving to the root folder, whose
location is detected by checking if "configure" exists two times in a
row. So, calling the installation script from src/tools/msvc/ with an
extra "configure" file four levels up the root path of the code tree
causes the execution to go further up, leading to a failure in finding
the builds. This commit fixes the issue by moving to the root folder of
the code tree only once, when necessary.

IANA tzcode release 2019b adds an option that tells zic not to emit
the old 32-bit section of the timezone files, and to skip some other
space-wasting hacks needed for compatibility with old timezone client
libraries. Since we only expect our own code to use the timezone data
we install, and our code is up-to-date with 2019b, there's no apparent
reason not to generate the smallest possible files.
Unfortunately, while the individual zone files do get significantly
smaller in many cases, they were not that big to begin with; which
means that no real space savings ensues on filesystems that don't
optimize small files. (For instance, on ext4 with 4K block size,
"du" says the installed timezone tree is the same size as before.)
Still, it seems worth making the change, if only because this is
presumably the wave of the future. At the very least, we'll save
some cycles while reading a zone file.
But given the marginal value and the fact that this is a new code
path, it doesn't seem worth the risk of back-patching this change
into stable branches. Hence, unlike most of our timezone-related
changes, apply to HEAD only.

Contrary to the comment on 772d4b76, only paths starting with "./" or
"../" are considered relative to the current working directory by perl's
"do" function. So this patch converts all the relevant cases to use "./"
paths. This only affects MSVC.
Backpatch to all live branches.
Instead of running a SQL script to create the standard conversion
functions and pg_conversion entries, put those entries into the
initial data in postgres.bki.
This shaves a few percent off the runtime of initdb, and also allows
accurate comments to be attached to the conversion functions; the
previous script labeled them with machine-generated comments that
were not quite right for multi-purpose conversion functions.
Also, we can get rid of the duplicative Makefile and MSVC perl
implementations of the generation code for that SQL script.
A functional change is that these pg_proc and pg_conversion entries
are now "pinned" by initdb. Leaving them unpinned was perhaps a
good thing back while the conversions feature was under development,
but there seems no valid reason for it now.
Also, the conversion functions are now marked as immutable, where
before they were volatile by virtue of lacking any explicit
specification. That seems like it was just an oversight.
To avoid using magic constants in pg_conversion.dat, extend
genbki.pl to allow encoding names to be converted, much as it
does for language, access method, etc names.

Commit 3a7cc727c was a little over eager about adding an explicit return
to this function, whose value is checked in most call sites. This change
reverses that and returns the expected value explicitly. It also adds a
check to the one call site lacking one.
This complies with the perlcritic policy
Subroutines::RequireFinalReturn, which is a severity 4 policy. Since we
only currently check at severity level 5, the policy is raised to that
level until we move to level 4 or lower, so that any new infringements
will be caught.
A small cosmetic piece of tidying of the pgperlcritic script is
included.

The vertical tightness settings collapse vertical whitespace between
opening and closing brackets (parentheses, square brakets and braces).
This can make data structures in particular harder to read, and is not
very consistent with our style in non-Perl code. This patch restricts
that setting to parentheses only, and reformats all the perl code
accordingly. Not applying this to parentheses has some unfortunate
effects, so the consensus is to keep the setting for parentheses and not
for the others.
The diff for this patch does highlight some places where structures
should have trailing commas. They can be added manually, as there is no
automatic tool to do so.

Maintainers of out-of-tree PLs typically need access to the set of

Somehow, we'd missed ever doing this. The consequences aren't too
severe: basically, the timezone library would fall back on its hardwired
notion of the DST transition dates to use for a POSIX-style zone name,
rather than obeying US/Eastern which is the intended behavior. The net
effect would only be to obey current US DST law further back than it
ought to apply; so it's not real surprising that nobody noticed.

Backpatch through 9.1
Previously, each subroutine in initdb fired up its own standalone backend
session. Over time we'd grown as many as fifteen of these sessions,
and the cumulative startup and shutdown work for them was getting pretty
noticeable. Combining things so that all these steps share a single
backend session cuts a good 10% off the total runtime of initdb, more
if you're not fsync'ing.
The main stumbling block to doing this before was that some of the sessions
were run with -j and some not. The improved definition of -j mode
implemented by my previous commit makes it possible to fix that by running
all the post-bootstrap steps with -j; we just have to use double instead of
single newlines to end command strings. (This is only absolutely necessary
around the VACUUM and CREATE DATABASE steps, since those can't be run in a
transaction block. But it seems best to make them all use double newlines
so that the commands remain separate for error-reporting purposes.)
A minor disadvantage is that since initdb can't tell how much of its
output the backend has executed, we can no longer have the per-step
progress reporting initdb used to print. But things are fast enough
nowadays that that's not really all that useful anyway.
In passing, add more const decoration to some of the static arrays in
initdb.c.
This code relied on knowing exactly where in the source tree temporary
installations might appear. A reasonable hacker may not think to update
this code when adding use of a temporary installation, making it
fragile. Observe that commit 9fa8b0ee90
broke it unnoticed, and commit dcae5facca
fixed it unnoticed. Back-patch to 9.5 only; use of temporary
installations is unlikely to change in released versions.
With this patch the MSVC build and installation will work correctly with
the transforms. However the python transform tests for hstore and ltree
are still disabled pending some further adjustments.

Since commit cb4a3b04 we were already doing this for the Cygwin/mingw
toolchains, but MSVC had not been updated to do it. At Install.pm time,
the Makefile (or GNUmakefile) is inspected, and if a line matching
SO_MAJOR_VERSION is found (indicating a shared library is being built),
then files with the .dll extension are set to be installed in bin/
rather than lib/, while files with .lib extension are installed in lib/.
This makes the MSVC toolchain up to date with cygwin/mingw.
This removes ad-hoc hacks that were copying files into bin/ or lib/
manually (libpq.dll in particular was already being copied into bin).
So while this is a rather ugly kludge, it's still cleaner than what was
there before.

Unlike "make" itself, the MSVC build process recognized a continuation
even with whitespace after the backslash. (Due to a typo, some code
sites accepted the letter "s" instead of whitespace). Also, it would
consume any number of newlines following a single backslash. This is
mere cleanup; those behaviors were unlikely to cause bugs.
The recent addition of regression tests to uuid-ossp exposed the fact
that the MSVC build system wasn't being consistent about whether it was
building/testing that contrib module, ie, it would try to test the module
even when it hadn't built it. The same hazard was latent for sslinfo.
For the moment I just copied the more up-to-date logic from point A to
point B, but this is screaming for refactoring.
