Per the pg_locks documentation: Every transaction holds an exclusive lock on its transaction ID for its entire duration. If one transaction finds it necessary to wait specifically for another transaction, it does so by attempting to acquire share lock on the other transaction ID. That will succeed only when the other transaction terminates and releases its locks. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 8: explain analyze is your friend
