so that we close and flush the doomed relation's relcache entry before we start to delete the underlying catalog rows, rather than afterwards. For awhile yesterday I thought that an unexpected relcache entry rebuild partway through this sequence might explain the infrequent parallel regression failures we were chasing. It doesn't, mainly because there's no CommandCounterIncrement in the sequence and so the deletions aren't "really" done yet. But it sure seems like trouble waiting to happen.

relcache entries. Also, change TransactionIdIsCurrentTransactionId() so that if consulted during transaction abort, it will not say that the aborted xact is still current. (It would be better to ensure that it's never called at all during abort, but I'm not sure we can easily guarantee that.) In combination, these fix a crash we have seen occasionally during parallel regression tests of 8.0.

from being accepted after the outer right brace. Per report from Markus Bertheau. Also add regression test cases for this change, and for previous recent array literal parser changes.

if the target PID is a PG postmaster or backend --- for our purposes that is actually better than the Unix behavior. Per Dave Page and Andrew Dunstan.

PROCLOCK structs in shared memory now have only a bitmask for held locks, rather than counts (making them 40 bytes smaller, which is a good thing). Multiple locks within a transaction are counted in the local hash table instead, and we have provision for tracking which ResourceOwner each count belongs to. Solves recently reported problem with memory leakage within long transactions.

for every command executed within a transaction. For long transactions this was a significant memory leak. Instead, we can delete a portal's or subtransaction's ResourceOwner immediately, if we physically transfer the information about its locks up to the parent owner. This does not fully solve the leak problem; we need to do something about counting multiple acquisitions of the same lock in order to fix it. But it's a necessary step along the way.

ColLabel instead of just ColId --- that is, any keyword can appear after a dot and it will be taken as an identifier. Fixes problems with names that are okay as standalone function names but fail when qualified.

updates are no longer WAL-logged nor even fsync'd; we do not need to, since after a crash no old pg_subtrans data is needed again. We truncate pg_subtrans to RecentGlobalXmin at each checkpoint. slru.c's API is refactored a little bit to separate out the necessary decisions.

RecentXmin (== MyProc->xmin). This ensures that it will be safe to truncate pg_subtrans at RecentGlobalXmin, which should largely eliminate any fear of bloat. Along the way, eliminate SubTransXidsHaveCommonAncestor, which isn't really needed and could not give a trustworthy result anyway under the lookback restriction. In an unrelated but nearby change, #ifdef out GetUndoRecPtr, which has been dead code since 2001 and seems unlikely to ever be resurrected.
