Shut down postgresql and make a full filesystem copy of the PGDATA directory. This will ensure that anything else you do won't leave you in a worse position. 2. Upgrade to the latest version of postgresql 7.3, which is 7.3.21 3. Start up again 4. Try to fix the problem: a. see if there are any indexes on the table b. if so, drop them c. try to get a good logical backup using pg_dump. You may want to disable index scans by using "SET enable_indexscan = f;". d. If that doesn't work, you may have catalog corruption. Examine the catalogs (documented here: http://www.postgresql.org/docs/7.3/static/catalogs.html ), and look entries related to your table in pg_class and pg_index, and see if anything looks wrong. e. start from a fresh install and restore using the logical backup 5. Upgrade all data to a recent version of postgresql. You're on a really ancient version that has fallen out of official support. This may require several upgrade steps, but you should get upgraded to 8.3.8 or 8.4.1. A lot of bugs have been fixed, and as long as you are on 7.3, you will still be at serious risk.
