Check:
1) the listen_address='*' didn't "take". Make sure you remembered to
remove the comment sign (yup, i've seen that mistake manu times). Also,
you need to restart the service after you've changed that, perhaps you
forgot it?
2) Is there any chance that the postmaster is running on a non-default
port? Or that the client is connecting on a non-standard port?
3) Verify that the IP Npgsql connects to is correct. If you're using a
DNS name, make sure it resolves right.

If all those look right, run a "netstat -na" on the commandline and see
if there is a listener to port 5432 and what IP that one is bound to.
