I looked at pg_locks for one hung update to tb_entity, and it said it had an un-granted lock of type transactionid, for another transaction ID. I wanted to see what was happening in that transaction ID that might be causing this lock to be held, but I was unsure how. I know I can look in pg_locks for the other transaction, but that will not tell me what statement is executing in that transaction. pg_stat_activity does not have a transaction ID column. How can I see what statement is executing in a transaction? -- Moshe Jacobson Nead Werx, Inc. | Manager of Systems Engineering 2323 Cumberland Parkway, Suite 201 | Atlanta, GA 30339 mo...@neadwerx.com | www.neadwerx.com "Quality is not an act, it is a habit." -- Aristotle
