Do other tables have foreign key references to the table you're deleting from? If so, are there indexes on the foreign key columns? Do you have triggers or rules on the table? Have you queried pg_locks during the long-lasting deletes to see if the deleting transaction is waiting for a lock on something? > I rememeber having tried to delete the content of my table (IC) from > PgAdminIII and I took couples of seconds!!! Not minutes. How many records did you delete in this case? If there are foreign key references, how many records were in the referencing tables? How repeatable is the disparity in delete time? A single test case might have been done under different conditions, so it might not mean much. No offense intended, but "I remember" doesn't carry as much weight as a documented example. -- Michael Fuhr http://www.fuhr.org/~mfuhr/ ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
