In XidInMVCCSnapshot, it will check xid from tuple if is in snapshot->subxip. It means tuple store subtransaction?
But in PushTransaction, I see TransactionState.subTransaction will assign currentSubTransactionId, currentSubTransactionId will reinitialize in StartTransaction. So I think tuple should not store subtransaction id. I am confuse about this. If subtransaction id will reinitialize every start time. How to judge it is a subtransaction from xid in tuple? -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
