I ran VACUUM FULL ANALYZE yesterday and the re-ran the query with EXPLAIN ANALYZE. I got the same query plan and execution time.

It sure looks like the planner thinks the tables are a couple of orders of magnitude smaller than they actually are. Certainly the estimated sizes of the joins are way off :-( If you did analyze, it might help to increase the statistics target and re-analyze. regards, tom lane ************************************* This e-mail may contain privileged or confidential material intended for the named recipient only.
