Per recent work by Peter Geoghegan, it's significantly faster to
tuplesort on a single sortkey if ApplySortComparator is inlined into
quicksort rather reached via a function pointer. It's also faster
in general to have a version of quicksort which is specialized for
sorting SortTuple objects rather than objects of arbitrary size and
type. This requires a couple of additional copies of the quicksort
logic, which in this patch are generate using a Perl script. There
might be some benefit in adding further specializations here too,
but thus far it's not clear that those gains are worth their weight
in code footprint.
This provides a separate exception class for each error code that the
backend defines, as well as the ability to get the SQLSTATE from the
exception object.

src/pl/plpgsql/src/plerrcodes.h, src/include/utils/errcodes.h, and a
big chunk of errcodes.sgml are now automatically generated from a single
file, src/backend/utils/errcodes.txt.

Look only at the non-localized part of the output from "vcbuild /?",
which is used to determine the version of Visual Studio in use. Different
languages seem to localize different amounts of the string, but we assume
the part "Microsoft Visual C++" won't be modified.
and allow using config.pl to override the defaults. config.pl is removed from
the repository, so changes there will no longer show up when doing diff, and
will not prevent switching branches and such things.
config.pl would normally be used to override single values, but if an
old-style config.pl is read, it will override the entire default configuration,
making it backwards compatible.
pg_attribute, by having genbki.pl derive the information from the various
catalog header files. This greatly simplifies modification of the
"bootstrapped" catalogs.
This patch finally kills genbki.sh and Gen_fmgrtab.sh; we now rely entirely on
Perl scripts for those build steps. To avoid creating a Perl build dependency
where there was not one before, the output files generated by these scripts
are now treated as distprep targets, ie, they will be built and shipped in
tarballs. But you will need a reasonably modern Perl (probably at least
5.6) if you want to build from a CVS pull.
The changes to the MSVC build process are untested, and may well break ---
we'll soon find out from the buildfarm.
John Naylor, based on ideas from Robert Haas and others
in pg_proc. Also make it not emit duplicate extern declarations, and make it
a bit more bulletproof in some other small ways. Likewise fix the equally
hard-wired, and utterly undocumented, knowledge in the MSVC build scripts.
For testing purposes and perhaps other uses in future, pull out that portion
of the MSVC scripts into a standalone perl script equivalent to
Gen_fmgrtab.sh, and make it generate actually identical output, rather than
just more-or-less-the-same output.
Motivated by looking at Pavel's variadic function patch. Whether or not
that gets accepted, we can be sure that pg_proc's column set will change
again in the future; it's time to not have to deal with this gotcha.
any hardcoding of those options. Along the way, reorder the expression used to
calculate RELSEG_SIZE to make it slightly clearer. For now wal_segsize is only
allowed to have a value of 1 on Windows - we can relax that when we get full
large file support in the backend.

Only builds properly with MSVC for now.
ecpglib supports it.
Change configure (patch from Bruce) and msvc build system to no longer require
pthreads on win32, since all parts of postgresql can be thread-safe using the
native platform functions.
