That doesn't make sense at all.
That is just a bad habit from MySQL world. People just don't understand that all possible recovery is handled by postgres itself.
OTOH, there could be some consistency check method... If postgres had block- or row-level checksums, this could do. The best way I know is to do plain pg_dumpall. But this does not detect all data corruptions.
