Yeah, and extra 0 jumped in there. Faulty keyboard I guess. :) OS and everything but base is on the RAID-1. > This is very helpful.

It's worked quite well for us. -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
