In this case, not only is there not a lot of difference, but the difference is in the wrong direction. You need to fix that --- perhaps increasing stats targets would help? A more radical question is whether you have a well-chosen set of indexes in the first place. These two seem a bit odd, and certainly not terribly well matched to this query. regards, tom lane -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
