e1d55f7917 When positioned before the start of a ResultSet issuing relative(0) 
results in an exception being thrown when it really should be a
no-op.

2a35291952 Don't try to constant-fold functions returning RECORD, since the optimizer 
isn't presently set up to pass them an expected tuple descriptor.  Bug has
been there since 7.3 but was just recently reported by Thomas Hallgren.

29028762a9 Make constant-folding produce sane output for COALESCE(NULL,NULL), 
that is a plain NULL and not a COALESCE with no inputs.  Fixes crash
reported by Michael Williamson.

5c5c797cb2 In cost_mergejoin, the early-exit effect should not apply to the 
outer side of an outer join.  Per andrew@supernews.

3ea32d7b1f Flush any remaining statistics counts out to the collector at process 
exit.  Without this, operations triggered during backend exit (such as
temp table deletions) won't be counted ... which given heavy usage of
temp tables can lead to pg_autovacuum falling way behind on the need
to vacuum pg_class and pg_attribute.  Per reports from Steve Crawford
and others.

3e65431bc1 array_map can't use the fn_extra field of the provided fcinfo struct as 
its private storage, because that belongs to the function that it is
supposed to call.  Per report from Ezequiel Tolnay.

b4fd104204 Previous "64-bit fix" for intagg didn't actually work. This is already 
fixed properly in CVS tip, but we need a band-aid for back branches.

80fba0f8ee Fix ALTER DATABASE RENAME to allow the operation if user is a superuser 
who for some reason isn't marked usecreatedb.  Per report from Alexander
Pravking.  Also fix sloppy coding in have_createdb_privilege().

2450224e6b Some builds (depends on crypto engine support?) of OpenSSL 
0.9.7x have EVP_DigestFinal function which which clears all of
EVP_MD_CTX.  This makes pgcrypto crash in functions which
re-use one digest context several times: hmac() and crypt()
with md5 algorithm.

Following patch fixes it by carring the digest info around
EVP_DigestFinal and re-initializing cipher.

89dcff555f Release proclock immediately in RemoveFromWaitQueue() if it represents 
no held locks.  This maintains the invariant that proclocks are present
only for procs that are holding or awaiting a lock; when this is not
true, LockRelease will fail.  Per report from Stephen Clouse.

overrunning the array, not after.

5c057d4b44 Prevent 4 more buffer overruns in the PL/PgSQL parser. This is just a 
minimally-invasive fix for stable branches; a cleaner fix will be
committed to HEAD soon.

3f8235ba24 Repair CLUSTER failure after ALTER TABLE SET WITHOUT OIDS. Turns out 
there are corner cases involving dropping toasted columns in which the
previous coding would fail, too: the new version of the table might not
have any TOAST table, but we'd still propagate possibly-wide values of
dropped columns forward.

that it is shorter and faster.  Per report from Charles Haron.

3b01217d7d Prevent overrunning a heap-allocated buffer if more than 1024 parameters

de68155298 Use StrNCpy not strncpy to fill hash key, to ensure the resulting key 
is null-terminated.  I think this is not a real bug because the parser
would always have truncated the identifier to NAMEDATALEN-1 already,
but let's be safe.  Per report from Klocwork.

0b9f48daf2 Avoid scribbling on original parsetree during DECLARE CURSOR. This

f5778c63e5 Install Tcl regex fixes to sync our regex engine with Tcl 8.4.8 (up from

issue I was hoping to find a solution for :-(
