Since evt_id is a bigint, you need to write that as select evt_id from event_tbl where evt_id=1::bigint; or various other locutions that have the same effect. What you have is a bigint-vs-int comparison, which is not indexable in releases before 8.0. The same problem is occurring in your other example. regards, tom lane ---------------------------(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
