Have you tuned your postgresql.conf settings ? The PostgreSQL default settings are very low in order to allow PostgreSQL to RUN on old machines and new machines. If you need PERFORMANCE (which is quite logic), you must setup the postgresql.conf file. Here's a nice article about the postgresql.conf file tuning : http://www.varlena.com/varlena/GeneralBits/Tidbits/perf.html Hope this help ! :-) Cheers, --------------------------------------- Bruno BAGUETTE - [EMAIL PROTECTED] ---------------------------(end of broadcast)--------------------------- TIP 9: the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
