a44f99024c Updatable ResultSets need to check for an empty ResultSet because 
isBeforeFirst and isAfterLast both return false for an empty result
so the checking to make sure the user is on a valid row wasn't
working.

Also don't allow an insert without specifying at least one column
value because INSERT INTO tab() values() is a syntax error.

f5517ddbda When moveToCurrentRow is called and the current row is off the 
end of the ResultSet we can't try to load that row because it
doesn't exist and will throw an Exception.

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

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.

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.

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.

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.
