If that doesn't force it into an indexscan, then you have got more fundamental issues (perhaps a datatype mismatch). Note that I don't recommend turning off enable_seqscan as a production solution; but it's a useful tool for debugging. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to majordomo@xxxxxxxxxxxxxx
