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

Add the current xlog insert location to the response of
IDENTIFY_SYSTEM, and adds result sets containing start
and stop location of backups to BASE_BACKUP responses.
Prior to 9.0, restartpoints never created, deleted, or recycled WAL
files, but now they can. This code makes log_checkpoints treat
checkpoints and restartpoints symmetrically. It also adjusts up
the documentation of the parameter to mention restartpoints.
Fujii Masao. Docs by me, as suggested by Itagaki Takahiro.
This allows the language-specific try/catch construct to catch and
handle exceptions arising from SPI calls, matching the behavior of
other PLs.
As an additional bonus you no longer get all the ugly "unrecognized
error in PLy_spi_execute_query" errors.

This is an efficiency change, and means we now no longer have to run
"out $_TD; local $_TD = shift;", which was especially pointless in the case of
non-trigger functions where the passed value was always undef anyway.
A tiny open issue is whether we should get rid of the $prolog argument of
mkfunc, and the corresponding pushed value, which is now just a constant "false".

New versions of libintl redefine setlocale() to a macro
which causes problems when the backend and libintl are
linked against different versions of the runtime, which
is often the case in msvc builds.

Unlike Btree-based LIKE optimization, this works for non-left-anchored
search patterns. The effectiveness of the search depends on how many
trigrams can be extracted from the pattern. (The worst case, with no
trigrams, degrades to a full-table scan, so this isn't a panacea. But
it can be very useful.)

Previously reported as ERRCODE_ADMIN_SHUTDOWN, this case is now
reported as ERRCODE_T_R_DATABASE_DROPPED. No message text change.
Unlikely to happen on most servers, so low impact change to allow
session poolers to correctly handle this situation.

All retryable conflict errors now have an error code that indicates that
a retry is possible, correcting my incomplete fix of 2010/05/12

Remove recommendation against using Mingw as a build platform.
Be more specific about when Cygwin is useful and when it's not, in
particular note its usefulness for running psql, and
add a note about building on Cygwin in non-C locales.
