Before looking at it as a driver problem, try telneting to the port
on the machine from the machine you are trying to run it on. ie...
Sys-A$ telnet Sys-B 5432
If it can't connect, then it is a network problem, like the firewall
etc getting in your way.
No route to host though sounds like the System-A has no routing information
about how to get to System-B, never mind the getting to a port on it. You
may need to add a static route... It doesn't look like a pgsql problem
