Also, I'd try running a large, long running pgbench test to see if you get any errors. If such a simple schema / operation in large scale gets errors it's almost certainly a hardware failure.
Have you had power removed while the system was running? With a lot of direct attached SATA drives you can get corruption from that as well due to linux / sata often not obeying write barriers. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
