Are you connecting over a network?

In other words is pgAdmin on one machine and the server on another?

If so is there a firewall in between that is blocking access to port 5432?

If not can you explain more about what your setup is?

Probably, because what you showed doesn't include any line permitting
external connections; but that's not your problem yet.  "Connection
refused" is a network-level error: your connection is never getting to the
Postgres server.  Double-check addresses, check network connectivity,
check firewall settings.  My first bet is you need to poke a hole in the
server machine's firewall --- see iptables or local equivalent.  Another
possibility is that the server's listen_addresses setting only tells it
to listen for local TCP connections not remote ones.  You typically want
listen_addresses set to "*" if you intend to allow remote connections.

When you start getting complaints phrased along the lines of "no
pg_hba.conf entry" then it'll be time to fix pg_hba.conf.
