Hi, thanks for the reply! > What are you using it for?
I want to use it to validate status of related entities in other database (queue) in short interval after PG transaction commit/rollback. > I can't reproduce that... Yes, it happens only with one cluster. All others work as expected. > Your mailer appears to do very annoying things by converting numbers to phone numbers. Sorry. > It's from the last epoch. Plain xids are 32bit wide, the epochs deal > with values that are bigger. And 2207340131 is less than 2^31 in the > past. Yes, and probably it is cause of the issue. ShmemVariableCache->oldestClogXid = 2207340131 xid_epoch = 1 xid = 150227913 TransactionIdPrecedes(xid, ShmemVariableCache->oldestClogXid)) return TRUE , then TransactionIdInRecentPast return FALSE and txtd_status return NULL. But xid (1) and xid_epoch (150227913) are correct values from my active (or recently commited) transaction. >> SELECT txid_status(BIGINT '4294967295') -> 'commited'. >> SELECT txid_status(BIGINT '4294967296') -> NULL > Why do you think that is the wrong result? Let's leave it for now (maybe my misunderstanding). I think it is better to deal with "txid_status(txid_current()) -> NULL" issue first. Thanks, Michail.
