If you know the md5 hash, you know everything the postmaster does, so
it's hard to see where such an attacker is going to be stopped. The
entire point here is not to expose the cleartext password, and that
really has nothing to do with whether you're going to break into the
PG database. It's about protecting users who are foolish enough to
use the same cleartext password for multiple services.
