release it in a subtransaction abort, but this neglects possibility that
someone outside SPI already did. Fix is for spi.c to forget about a tuptable
as soon as it's handed it back to the caller.
Per bug #2817 from Michael Andreen.
rearrangeable outer joins and the WHERE clause is non-strict and mentions
only nullable-side relations. New bug in 8.2, caused by new logic to allow
rearranging outer joins. Per bug #2807 from Ross Cohen; thanks to Jeff
Davis for producing a usable test case.
a sublink's test expression have the correct vartypmod, rather than defaulting
to -1. There's at least one place where this is important because we're
expecting these Vars to be exactly equal() to those appearing in the subplan
itself. This is a pretty klugy solution --- it would likely be cleaner to
change Param nodes to include a typmod field --- but we can't do that in the
already-released 8.2 branch.
Per bug report from Hubert Fongarnand.
identify long-running transactions. Since we already need to record
the transaction-start time (e.g. for now()), we don't need any
additional system calls to report this information.
Catversion bumped, initdb required.
capitalize the strings like sentences. Remove unnecessarily
specific descriptions of the units used by GUC variables, since
we now allow any reasonable unit to be specified.
FormatMessage() (This should have been in 8.2.0, patched to 8.2.X and
HEAD):

FormatMessage of windows cannot consider the encoding of the database.
However, I should try the solution now. It is necessary to clear the
problem.
Multi character-code exists together in message and log. It doesn't
consider
the data base encoding that the user intended....
The user in multi-byte country can try this.

should allow delete-pending files to actually go away, and thereby work
around the various complaints we've seen about 'permission denied'
errors in such cases. Should be reasonably harmless in any case...
StartupXLOG and ShutdownXLOG no longer need to be critical sections, because
in all contexts where they are invoked, elog(ERROR) would be translated to
elog(FATAL) anyway. (One change in bgwriter.c is needed to make this true:
set ExitOnAnyError before trying to exit. This is a good fix anyway since
the existing code would have gone into an infinite loop on elog(ERROR) during
shutdown.) That avoids a misleading report of PANIC during semi-orderly
failures. Modify the postmaster to include the startup process in the set of
processes that get SIGTERM when a fast shutdown is requested, and also fix it
to not try to restart the bgwriter if the bgwriter fails while trying to write
the shutdown checkpoint. Net result is that "pg_ctl stop -m fast" does
something reasonable for a system in warm standby mode, and so should Unix
system shutdown (ie, universal SIGTERM). Per gripe from Stephen Harris and
some corner-case testing of my own.

result now depends on the lc_messages setting, as noted by Bruce.
Also, mark to_number() and the numeric-type variants of to_char() as stable,
because their results depend on lc_numeric; this is a longstanding oversight.
Also, mark to_date() and to_char(interval) as stable; although these appear
not to depend on any GUC variables as of CVS HEAD, that seems a property
unlikely to survive future improvements. It seems best to mark all the
formatting functions stable and be done with it.
catversion not bumped, because this does not seem critical enough to force
a post-RC1 initdb, and anyway we cannot do so in the back branches.
(in particular, causing the ReadyForQuery message to be eaten) before
returning from do_copy. The only known consequence of failing to do so is
that get_prompt might show a wrong result for the %x transaction status
escape, as reported by Bernd Helmle; but it's possible there are other issues.
Back-patch as far as 7.4, the oldest version supporting %x.
vacuum/analyze timestamp columns at the end, rather than at a random
spot in the middle as in the original patch. This was deemed more usable
as well as less likely to break existing application code. initdb forced
accordingly. In passing, remove former kluge for initializing
pg_stat_file()'s pg_proc entry --- bootstrap mode was fixed recently
so that this can be done without any hacks, but I overlooked this usage.
HeapTuple that is no longer allocated as a single palloc() block; if
used carelessly, this might result in a subsequent memory leak after
heap_freetuple().
AbortTransaction, which would lead to recursion and eventual PANIC exit
as illustrated in recent report from Jeff Davis. First, in xact.c create
a special dedicated memory context for AbortTransaction to run in. This
solves the problem as long as AbortTransaction doesn't need more than 32K
(or whatever other size we create the context with). But in corner cases
it might. Second, in trigger.c arrange to keep pending after-trigger event
records in separate contexts that can be freed near the beginning of
AbortTransaction, rather than having them persist until CleanupTransaction
as before. Third, in portalmem.c arrange to free executor state data
earlier as well. These two changes should result in backing off the
out-of-memory condition before AbortTransaction needs any significant
amount of memory, at least in typical cases such as memory overrun due
to too many trigger events or too big an executor hash table. And all
the same for subtransaction abort too, of course.
zic's Europe/London, rather than Europe/Dublin as before. This seems
a less surprising choice, particularly with respect to dates before
1948. Original suggestion was to translate to straight GMT, but this
seems wrong given that these zones *are* DST-aware. Per offlist
discussion with Magnus.
in the middle of executing a SPI query. This doesn't entirely fix the
problem of memory leakage in plpgsql exception handling, but it should
get rid of the lion's share of leakage.
because on that platform strftime produces localized zone names in varying
encodings. Even though it's only in a comment, this can cause encoding
errors when reloading the dump script. Per suggestion from Andreas
Seltenreich. Also, suppress %Z on Windows in the %s escape of
log_line_prefix ... not sure why this one is different from the other two,
but it shouldn't be.
python 2.5. This involves fixing several violations of the published

Windows), arrange for each postmaster child process to be its own process
group leader, and deliver signals SIGINT, SIGTERM, SIGQUIT to the whole
process group not only the direct child process. This provides saner behavior
for archive and recovery scripts; in particular, it's possible to shut down a
warm-standby recovery server using "pg_ctl stop -m immediate", since delivery
of SIGQUIT to the startup subprocess will result in killing the waiting
recovery_command. Also, this makes Query Cancel and statement_timeout apply
to scripts being run from backends via system(). (There is no support in the
core backend for that, but it's widely done using untrusted PLs.) Per gripe
from Stephen Harris and subsequent discussion.
Typo in the changes to plperl - uses wrong dir, and had a missing slash.
Also fixes error checking for xsubpp - it was broken in a way that hid
the problem above when run more than once (which is the normal case when
developing).
