Unless you were running with fsync = off or full_page_writes = off, that should not happen. It is likely to be caused by a hardware problem (bad RAM, a bad disk drive, or network problems if your storage is across a network). If it were me, I would stop the database service and copy the full data directory tree. http://wiki.postgresql.org/wiki/Corruption If fsync or full_page_writes were off, your best bet is probably to go to your backup. If you don't go to a backup, you should try to get to a point where you can run pg_dump, and dump and load to a freshly initdb'd cluster. If fsync and full_page_writes were both on, you should run hardware diagnostics at your earliest opportunity. When hardware starts to fail, the first episode is rarely the last or the most severe. -- Kevin Grittner EDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
