True.  Encrypted communication should be an option, though.  With
Kerberos, the ability to do this securely is already there in the
library, so it would be natural to use it.  Adding encryption to the
communication between client and postmaster is probably a good thing
even if we don't (yet) encrypt that between client and backend, and
would also be a good, simple way to start implementing it.
