Um ... I've taken that tack in the past, and every time I have, other
people have asserted that SSH tunnels are hard or impossible to set up
in their environments (eg, they're running Windows clients, don't want
to grant users shell accounts on the db server, etc).  Got to listen
to the customers.

I think it would be a mistake to make usage of SSL for simple comsec
significantly harder to set up than it is now.  People who want to have
authentication and so on can be told how to do it right, but don't force
your views of the right way to do things on everyone.

Isn't that fixed as of 7.2?  We don't do SSL negotiations in the
postmaster anymore.
