It probably can't tell if > is selective enough to justify using index. Together with "limit 10" it may be. You could try explain analyze select * from forecastelement where valid_time between '2004-01-22'::date and '2004-01-22'::date limit 10; to see if this is considered good enough. -------------- Hannu ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
