Perhaps you should send more details of the table definition and the typical size of each column. It's possible you have the columns you're selecting on being stored out of line ("toasted") which would hurt performance if you're often accessing many of those columns. If it's not true then you may have a lot of dead space in your table which would decrease performance. -- Gregory Stark EnterpriseDB http://www.enterprisedb.com ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
