The postgresql server must also be running SSH server. You use the SSH
client to forward the postgresql port to your local computer. Your
client computer does not need to have a domain name.

So for you the SSH comand line would be
ssh -v -L 5432:localhost:5432 dbuser(at)my(dot)pgserver(dot)com

You open your client and point it to localhost:5432

SSH is forwarding the distant 5432 port to your local computer through a
secure tunnel. This is totally transparent for server and client - the
server needs no configuration. You can forward the postgres port to
another port number if you wish (for example you are running a
postgresql server on your local machine too).
