If you tend to do lots of queries for the last 24 hours, and there is only a very small percentage of such young rows, partial indices could be helpful. You could include all rows that are not older than 24 hours, and recreate them via cron script daily, so they grow from 24 to 48 hours between recreations. To avoid a gap in recreation, you could first create the new index, and then drop the old one, using alternating names. BTW, a small question for the gurus: does postgres make use of other indices when creating partial indices?
