Well, it seems to connect:
foo$ psql -h localhost

I am not sure how to tinker with these conf files. The server policy
will not allow any non-local connection. But as a test case I can play
with the reverse connection - remote as client and local as the
server. I have full access to my local (bar) machine. As I said, the
errors are exactly similar.
Any pointers?
