The PostgreSQL server doesn't report such things directly, and I don't know pgadmin, so I don't know about that tool. I wrote the recursive query on this page: http://wiki.postgresql.org/wiki/Lock_dependency_information So if that reported anything incorrecly, please let me know so I can fix it. By the way, the example with the three connections would have been better had I suggested a BEGIN TRANSACTION ISOLATION LEVEL REPEATABLE READ; on the third connection. With that, even if one or both of the transactions on the other connections committed, the third transaction's count should remain unchanged. -Kevin -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
