Probably, you deleted the pg_shadow entry for the user that owned this
table. 7.1's pg_dump is somewhat smarter about this sort of situation,
but in older versions it doesn't cope well. Look in pg_class to see
what relowner the table has, and create a new user with matching sysid.
Or change the relowner to match the sysid of an existing user.
