You could try reindexing, but if pg_dump is failing that's a good sign you have heap corruption not (or at least not only) index corruption. Another idea is to try using contrib/pageinspect to examine each page of the table. Its output is just gobbledegook to most people, but there's a good chance it'd fail visibly on the corrupted page(s). Also, please read https://wiki.postgresql.org/wiki/Corruption if you didn't already. regards, tom lane
