If it's 8.2 or older, this probably indicates a partial block at the end of the file. Newer versions produce a more sensible error message for the case, but that's just cosmetic --- the real problem is a messed-up table. Have you had a filesystem corruption or an out-of-disk-space condition on this machine? regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
