This, implementation of a VPN or using the builtin ssl-support in
postgresql is the way to go, because *everything* that goes through
the channel will be encrypted. With SSL you have the additional value
of being able to guarantee the identity of the server.
The information in the source code distribution in
src/backend/libpq/README.SSL
might prove useful to make your decision.

Too weak, IMHO. md5 is there to protect the password data stored
in the database, not the password transmission (someone already
mentioned tcp replay attacks).
