I'm about to setup a similar config and what I was intending to do is to 
run pgpool on both boxes and use heartbeat (from http://linux-ha.org ) to 
move an IP address from one box to the other. clients connect to this 
virtual IP and then pgpool will distribute the connections to both systems 
from there.
