Once the patch is rewritten, yes, all fe/be communication will take
place in two functions, pq_read and pq_write.  It'll take a little
more to make it completely modularized (once bruce removes the exec()
it will make things much better -- as it is the SSL connection must be
renegotiated at that point) but I think it is worth the effort.  I may
go as far as to allow pluggable transport mechanisms and
authentication.

It's a work in progress.  The info page is at
http://www.chicken.org/pgsql/ssl/

It details some of the changes I plan to make, as well as a short
description of the patch and how I feel about the fe/be communication.
However, it is probably poorly written, so I should probably change
that.

I warn against using it at this point -- libpq is the only interface
guarunteed to work, which means no perl interface without some ugly
hacking.  This will change.
