Remopte connection to POstgreSQL via ODBC

Hello.

I just read all about TCP/IP, pg_hba.conf, listen_adresses and similar
topics regarding remote TCP/IP connections,
but where can I find explanations about how to remotely connect using
ODBC and DSN-less connection string.
For example, how to connect to PostgreSQL server from remote computer
using MS Access and DSN-less connection string ?
Since now, I successfully conected from MS Access using DSN-less
connection string but from the same machine. What if server is on a
remote computer ? Is there any guide?

Thanks in advance,

Zlatko
