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.

leak memory when printing a toasted attribute, and printtup_internal
didn't work at all...

since those routines may do palloc's.  We want to be fairly sure we can
send the error message to the client even under low-memory conditions.
That's what we stashed away 8K in ErrorContext for, after all ...

not-very-good handling of mid-size allocation requests.  Do everything via
either the "small" case (chunk size rounded up to power of 2) or the "large"
case (pass it straight off to malloc()).  Increase the number of freelists
a little to set the breakpoint between these behaviors at 8K.

immediately uncovered three of Karel's own bugs, including a routine
that scribbled on its input (naughty naughty!)

apply Karel Zak's patch to recycle residual space in an exhausted allocation
block.  (Bet you thought I'd forgot about that, Karel?)

I hope all the dust has settled out now ...

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

by without them.

Don't check for preprocessor symbols from system header files in port
include files, since those header files aren't included at this point.

$(CC) $(CFLAGS) $(LDFLAGS) <object files> <extra-libraries> $(LIBS) -o $@

This form seemed to be the most portable, readable, and logical, but in any
case it's better than having a dozen different ones in the tree.

both MULTIBYTE and TOAST prevent char(n) from being truly fixed-size.
Simplify and speed up fastgetattr() and index_getattr() macros by
eliminating special cases for attnum=1.  It's just as fast to handle
the first attribute by presetting its attcacheoff to zero; so do that
instead when loading the tupledesc in relcache.c.

does that.  Disable URL-style connection parameter specification code,
which doesn't work.

CommitDelay in guc.c

included by everything that includes bufmgr.h --- it's supposed to be
internals, after all, not part of the API!  This fixes the conflict
against FreeBSD headers reported by Rosenman, by making it unnecessary
for s_lock.h to be included by plperl.c.

   SetConfigOption(name, value,
        (IsUnderPostmaster) ? PGC_BACKEND : PGC_POSTMASTER);

postmaster, because it isn't updated after forking away from the terminal.
Apparently it's not used anyplace in the postmaster ... but seems best
to make it show the correct PID ...

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.)

information.

for a now-vanished group.  Instead, display the numeric group ID, same
as it does for vanished users.

IPC key assignment will now work correctly even when multiple postmasters
are using same logical port number (which is possible given -k switch).
There is only one shared-mem segment per postmaster now, not 3.
Rip out broken code for non-TAS case in bufmgr and xlog, substitute a
complete S_LOCK emulation using semaphores in spin.c.  TAS and non-TAS
logic is now exactly the same.
When deadlock is detected, "Deadlock detected" is now the elog(ERROR)
message, rather than a NOTICE that comes out before an unhelpful ERROR.
