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
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.
