ERROR: missing chunk number 0 for toast value

Hi,

I get the above error while selecting data from a table.
i have reindexed the table and possibly toast table
but it does not seems to help. result of  vacuum full is also
attached. can anyone please help. even pg_dump is not able to dump
the table.


pg_dump: ERROR:  missing chunk number 0 for toast value 697890392
pg_dump: SQL command to dump the contents of table "bad_emails"
failed: PQendcopy() failed.
pg_dump: Error message from server: ERROR:  missing chunk number
0 for toast value 697890392
