If you use the "classic" syntax as you described it, postgres will do its best to figure out the best join order. It probably couldn't hurt to try. When you say you created all the necessary indices, do you mean that all the fields used in the join criteria are indexed? ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to majordomo@postgresql.org
