These functions should take a pg_locale_t, not a collation OID, and should
call mbstowcs_l/wcstombs_l where available. Where those functions are not
available, temporarily select the correct locale with uselocale().
This change removes the bogus assumption that all locales selectable in
a given database have the same wide-character conversion method; in
particular, the collate.linux.utf8 regression test now passes with
LC_CTYPE=C, so long as the database encoding is UTF8.
I decided to move the char2wchar/wchar2char functions out of mbutils.c and
into pg_locale.c, because they work on wchar_t not pg_wchar_t and thus
don't really belong with the mbutils.c functions. Keeping them where they
were would have required importing pg_locale_t into pg_wchar.h somehow,
which did not seem like a good plan.
This adds collation support for columns and domains, a COLLATE clause
to override it per expression, and B-tree index support.

Synchronize pg_config.h.in with configure.in (someone must have
forgotten to run autoheader or autoreconf), and clean up some spurious
change in configure introduced by the last commit there.
compilers, by applying a configure check to see if the compiler will accept
an unreferenced "static inline foo ..." function without warnings. It is
believed that such warnings are the only reason not to declare inlined
functions in headers, if the compiler understands "inline" at all.

provide a working 64-bit integer datatype. As recently noted, we've been
broken on such platforms since early in the 8.4 development cycle. Since
it took nearly two years for anyone to even notice, it seems that the
rationale for continuing to support such platforms has reached the point
of non-existence. Rather than thrashing around to try to make it work
again, we'll just admit up front that this no longer works.
Back-patch to 8.4 since that branch is also broken.
We should go around to remove INT64_IS_BUSTED support, but just in HEAD,
so that seems like material for a separate commit.
This is more in keeping with modern practice, and is a first step towards
porting to Win64 (which has sizeof(pointer) > sizeof(long)).

append_history(), if libreadline is new enough to have those functions
(they seem to be present at least since 4.2; but libedit may not have them).
This gives significantly saner behavior when two or more sessions overlap in
their use of the history file; although having two sessions exit at just the
same time is still perilous to your history. The behavior of \s remains
unchanged, ie, overwrite whatever was there.

and extend configure to test for it properly instead of hard-wiring
an assumption that everybody but Windows has the rand48 functions.
(We do cheat to the extent of assuming that probing for erand48 will do
for the entire rand48 family.)
erand48() is unused as of this commit, but a followon patch will cause
GEQO to depend on it.

This upgrades the configure infrastructure to the latest Autoconf version.
Some notable news are:
- The workaround for the broken fseeko() test is gone.
- Checking for unknown options is now provided by Autoconf itself.
- Fixes for Mac OS X
we can get some buildfarm feedback about whether that function is still
problematic. (Note that the planned async-preread patch will not really
prove anything one way or the other in buildfarm testing, since it will
be inactive with default GUC settings.)
the * character at the beginning of a pattern, and it does not match
subdomains.
Since this means we no longer need fnmatch, remove the imported implementation
from port, along with the autoconf check for it.

Mark Wong, though I thought it better to call the switches after "wal" rather

support for a nonsegmented mode from md.c. Per recent discussions, there
doesn't seem to be much value in a "never segment" option as opposed to
segmenting with a suitably large segment size. So instead provide a
configure-time switch to set the desired segment size in units of gigabytes.
While at it, expose a configure switch for BLCKSZ as well.

where Datum is 8 bytes wide. Since this will break old-style C functions
(those still using version 0 calling convention) that have arguments or
results of these types, provide a configure option to disable it and retain
the old pass-by-reference behavior. Likewise, provide a configure option
to disable the recently-committed float4 pass-by-value change.

requires working support for large files in the operating system; at least for

- Change configure.in to use Autoconf 2.61 and update generated files.
- Update build system and documentation to support now directory variables
offered by Autoconf 2.61.
- Replace usages of PGAC_CHECK_ALIGNOF by AC_CHECK_ALIGNOF, now available
in Autoconf 2.61.
- Drop our patched version of AC_C_INLINE, as Autoconf now has the change.

right, there seems precious little reason to have a pile of hand-maintained
endianness definitions in src/include/port/*.h. Get rid of those, and make
the couple of places that used them depend on WORDS_BIGENDIAN instead.
This commit breaks any code that assumes that the mere act of forming a tuple
(without writing it to disk) does not "toast" any fields. While all available
regression tests pass, I'm not totally sure that we've fixed every nook and
cranny, especially in contrib.

standard functions like pow() are not special-cased by the compiler.
Per report from Andreas Lange that build fails on Solaris cc compiler

I'm worried that similar issues will arise with other compilers.
max_stack_depth is not set to an unsafe value.
This commit also provides configure-time checking for <sys/resource.h>,
and cleans up some perhaps-unportable code associated with use of that
include file and getrlimit().
Buildfarm results from 'gazelle' show that there are indeed libedit
versions for which history.h is a needed header, even though it's
apparently been dropped entirely in other versions. Grumble.
