Oh. You can't realistically do that from the level of individual ON INSERT/DELETE triggers --- as you've found out, you end up with about the same number of dead rows anyway. Collapsing a transaction's changes into a single row would require keeping some intra-transaction state, which is do-able at the C-code level but not from plpgsql. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
