Fix relcache to account properly for subtransaction status of 'new'
Tom Lane <tgl@sss.pgh.pa.us>
Fix relcache to account properly for subtransaction status of 'new' 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.
