SOLVED!!

I redid the iptables command because the line above is incorrect, it
should read:

# iptables -A INPUT -p tcp --destination-port 5432 -s x.x.x.x -j ACCEPT

Note that the previous rule had to be deleted which I did by editing
the file /etc/iptables/default and removing it and saving the file (I
think there is a safer way but I didn't know how and was afraid I
might remove the wrong rule).

Note also there are some differences between Ubuntu and Fedora, for
example the location of the rules file. If I have to do this again I
would save file /etc/iptabes/default before I start messing with it.

After deleting the old rule and making the corrected rule with the
iptables command I did:

# /etc/init.d/iptables save
# /etc/init.d/iptables restart

and I got in!

Thanks Thom.
