After that the most common causes for database corruption I've seen are bad RAM (ECC RAM is a requirement, not an option for a serious database server in my book), failing hard drives (use RAID and SMART monitoring, and have a sane hardware replacement policy), or buggy device drivers (pay attention to releases which fix bugs or security vulnerabilities which could affect you). It's getting rare to see this now, but it used to be common for some drives to lie to you about having written data when it was actually just in cache -- a good BBU RAID controller will go out of its way to keep the drives honest. -Kevin -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
