int8, int16, int32, int64 and separately uint8, uint16, uint32, uint64

The previous patch grouped:
int8, int16 and int32
uint8, uint16 and uint32
int64 and uint64  <-- this grouping is wrong on AIX 4.3.3 and below

If you prefer to make 4 groups out of this you could apply this patch.

out glibc doesn't actually export this variable, so we need a different
solution.

before.

Enabling this feature adds very light overhead of 1 select from pg_class on
first using of pl/tcl in backend if unknown suppport is really unused.
But pl/tcl with this support has very improved functionality.

Patch includes changes to documentation.

an already installed iODBC or unixODBC driver manager.  In particular,
use the include files provided by the driver manager over our own,
and use the odbcinst library of the driver manager rather than gpps.c.

Migrate portability sections common to several files into psqlodbc.h.

unicode-conversion is always on if --enable-multibyte is specified

for them, and making them just wastes time during backend startup/shutdown.
Also, remove compile-time MAXBACKENDS limit per long-ago proposal.
You can now set MaxBackends as high as your kernel can stand without
any reconfiguration/recompilation.

See attached revised patch. (I'm sure the configure.in stuff can be done
right/better, I'm just not enough of a autoconf guru to know what to
change it to.)

Now with documentation update and disabling of UTF conversion for Tcl <=8.0

places that were including the wrong files.

points out how silly it is to use Autoconf to test for a preprocessor
symbol, when one can equally easily #ifdef on the symbol itself.
Accordingly, revert configure to prior state and do it that way.

system supports SO_PEERCRED requests for Unix sockets.  This is an
amalgamation of patches submitted by Helge Bahmann and Oliver Elphick,
with some editorializing by yours truly.

Note: I didn't force an initdb, figuring that one today was enough.
However, there is a new function in pg_proc.h, and pg_dump won't be
able to dump partial indexes until you add that function.

a lie on many Unixen), invoke listen() with MIN(MaxBackends*2, 10000).
The clamp value 10000 is configurable in config.h.in, if that proves
to be necessary --- hopefully it won't.

when built against readline 4.2.  Specifically, it handles the deprecation
of

    filename_completion_function()

with preference for

    rl_filename_completion_function()

Although, I was motivated by Cygwin support, IMO this patch is appropriate
for all platforms.  To quote from the readline source:

    #if 0
    /* Backwards compatibility (compat.c).  These will go away sometime. */
    ...
    extern READLINE_EXPORT(char, *filename_completion_function) ...
    #endif

Note that this patch is modeled after the one by Peter Eisentraut for
completion_matches():

    http://www.ca.postgresql.org/~petere/readline42.html
I tested this patch under the following environments:

    Cygwin with readline 4.1
    Cygwin with readline 4.2
    Linux with readline 2.2.1
    Linux with readline 4.2

and it behaved as expected.

Use --enable-nls to turn it on; see installation instructions for details.
See developer's guide how to make use of it in programs and how to add
translations.

psql sources have been almost fully prepared and an incomplete German
translation has been provided.  In the backend, only elog() calls are
currently translatable, and the provided German translation file is more
of a placeholder.

a separate statement (though it can still be invoked as part of VACUUM, too).
pg_statistic redesigned to be more flexible about what statistics are
stored.  ANALYZE now collects a list of several of the most common values,
not just one, plus a histogram (not just the min and max values).  Random
sampling is used to make the process reasonably fast even on very large
tables.  The number of values and histogram bins collected is now
user-settable via an ALTER TABLE command.

There is more still to do; the new stats are not being used everywhere
they could be in the planner.  But the remaining changes for this project
should be localized, and the behavior is already better than before.

A not-very-related change is that sorting now makes use of btree comparison
routines if it can find one, rather than invoking '<' twice.

accepts nnnLL syntax for long long constants.  If so, decorate the CRC64
constants with LL to avoid warnings and/or erroneous results from certain
non-standards-compliant compilers.

waste of cycles on single-CPU machines, and of dubious utility on multi-CPU
machines too.
Tweak s_lock_stuck so that caller can specify timeout interval, and
increase interval before declaring stuck spinlock for buffer locks and XLOG
locks.
On systems that have fdatasync(), use that rather than fsync() to sync WAL
log writes.  Ensure that WAL file is entirely allocated during XLogFileInit.

eliminates a raft of portability issues, including whether sys_nerr
exists, whether the platform has any valid negative errnos, etc.  The
downside is minimal: errno shouldn't ever contain an invalid value anyway,
and if it does, reasonably modern versions of strerror will not choke.
This rangecheck idea seemed good at the time, but it's clearly a net loss,
and I apologize to all concerned for having ever put it in.

* doc/FAQ_MSWIN: Update to be consistent with software -- mainly change
comment from lack of Cygwin UNIX domain socket support and to list of
current Cygwin UNIX domain socket issues.
* src/include/config.h.in: Enable UNIX domain sockets for Cygwin.
* src/include/port/win.h: Disable UNIX domain sockets for Cygwin b20.1.
* src/test/regress/pg_regress.sh: Use UNIX domain sockets for Cygwin
instead of TCP/IP.

1. Distinguish cases where a Datum representing a tuple datatype is an OID
from cases where it is a pointer to TupleTableSlot, and make sure we use
the right typlen in each case.
2. Make fetchatt() and related code support 8-byte by-value datatypes on
machines where Datum is 8 bytes.  Centralize knowledge of the available
by-value datatype sizes in two macros in tupmacs.h, so that this will be
easier if we ever have to do it again.

anymore.  That won't teach us anything new for the rest of this release
cycle, so it seems better to keep the --assert environment more like the
non-assert environment for beta.
I'm going to leave CLOBBER_FREED_MEMORY and MEMORY_CONTEXT_CHECKING
turned on by --enable-cassert for now, however.

If we're going to let it be run-time configurable, might as well allow
this too...

socket file, in favor of having an ordinary lockfile beside the socket file.
Clean up a few robustness problems in the lockfile code.  If postmaster is
going to reject a connection request based on database state, it will now
tell you so before authentication exchange not after.  (Of course, a failure
after is still possible if conditions change meanwhile, but this makes life
easier for a yet-to-be-written pg_ping utility.)

'long long int' portions of ecpg if the type or these functions don't
exist.

to work everywhere.  Also, on FreeBSD you need to set the optreset variable
to 1 before parsing the command line a second time with getopt().

included, and then include <strings.h> if so.  Several systems already
needed <strings.h> anyway.  Some new systems that claim to conform to the
Unix 9x "standard" do not declare str[n]casemp() in string.h, and C99
compilers will not like that.

code conversion between Unicode and other encodings. Note that
this option requires --enable-multibyte also.
The reason why this is optional is that the feature requires huge
mapping tables and I don't think every user need the feature.
