It is, but again I tried that when I originally designed this and I think it ended up using seq scans, or at least being slow for some reason or other. But I'll be dropping this db into 8.4 soon to see if it helps anything, and I'll check again (and if it's still slow I'll post more details). It's been a while and I might just have been doing something wrong. -- Glenn Maynard -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
