I have a table with an INSERT/UPDATE/DELETE statement trigger. The trigger's action is to insert "jobs" into a queue noting that the table has changed.
A number of other tables have FK relationships with this table, and they have their own statement triggers that fire on DELETE. When I delete a number of rows from the first table, the cascading deletes into the other tables generate a rather large number of trigger-fires, so I end up with way too many rows in the queue-table. What I would like to do is, within the transaction doing the top-level delete, examine the queue-table for duplicate rows and remove those, since they are extraneous. Ideally I would look for rows that have the same transaction ID, but I'm having trouble determining what the current ID is. I'm using Pg 7.4. ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
