Actually, this begs the question: are there any "reverse DB" proxy
servers around that people have used?  Having a reverse libpq proxy
server would _rock_.  Some light weight multi-threaded proxy that
relays active connections to the backend and holds idle connections
more efficiently than PostgreSQL... well... it'd be a life saver in
sooooo many situations.  Granted it'd have its short comings
(connections would persist to the backend along transactions, once
committed, the front end would "detatch" from the backend that it was
using), but this is achitecturally similar to what MS and ORA do to
handle gazillions of connections to a database that in reality, can
only handle a few hundred (maybe a thousand or two) active
connections.
