There is not any easy way at the moment. Hmm ... I wonder how hard it would be to teach EXPLAIN ANALYZE to show the runtime expended in each trigger when the statement is of a kind that has triggers. We couldn't break down the time *within* the triggers, but even this info would help a lot in terms of finger pointing ... Seq Scan on ... (nn.nnn ms) Trigger foo: nn.mmm ms Trigger bar: nn.mmm ms Total time: nn.mmm ms regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
