This script is a bit slow, but still it only takes a fraction of the time
the bison run does, so the overhead doesn't seem intolerable. And we
definitely need some mechanical aid here, because people keep missing
the need to add new keywords to the appropriate keyword-list production.
While at it, I moved check_keywords.pl from src/tools into
src/backend/parser where it's actually used, and did some very minor
cleanup on the script.
This was removed in commit cd00406774,
we're not quite sure why, but there have been reports of crashes due
to AS Perl being built with it when we are not, and it certainly
seems like the right thing to do. There is still some uncertainty
as to why it sometimes fails and sometimes doesn't.
Original patch from Owais Khani, substantially reworked and
extended by Andrew Dunstan.
We seem to have a rough policy that our Perl scripts should work with
Perl 5.8, so make this one do so. Main change is to not use the newfangled
\h character class in regexes; "[ \t]" is a serviceable replacement.
This includes fixing the MSVC copy of ecpg/preproc's version info, which
seems to have been overlooked repeatedly. Can't we fix that so there are
not two copies??
The header file is needed by any module that wants to use the PL/pgSQL
instrumentation plugin interface. Most notably, the pldebugger plugin needs
this. With this patch, it can be built using pgxs, without having the full
server source tree available.
This makes it much more convenient to build tools for Postgres that are
separately compiled and require a matching CRC implementation.
To prevent multiple copies of the CRC polynomial tables being introduced
into the postgres binaries, they are now included in the static library
libpgport that is mainly meant for replacement system functions. That
seems like a bit of a kludge, but there's no better place.
This cleans up building of the tools pg_controldata and pg_resetxlog,
which previously had to build their own copies of pg_crc.o.
In the future, external programs that need access to the CRC tables can
include the tables directly from the new header file pg_crc_tables.h.

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.
