I'm not very familiar with > this table, what's the difference between transaction and transactionid? transaction is the Xid of the transaction holding or waiting for the lock. transactionid is not null in the case where the lock is for a TransactionId. I guess it depends on what do you want though -- now that I think about it, capturing only transaction locks is very likely not what you want. http://developer.postgresql.org/docs/postgres/view-pg-locks.html I wonder why do you have that condition though. I don't think "transaction" can ever be NULL in that view. -- Alvaro Herrera (<alvherre[a]alvh.no-ip.org>) "Hay dos momentos en la vida de un hombre en los que no deberÃa especular: cuando puede permitÃrselo y cuando no puede" (Mark Twain) ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
