Hi Dave,

I'm not entirely clear on your setup - I assume it's something like:

Dev Box -> Firewall -> PG Server

You then tunnel a connection to the firewall, which is then forwarded to
the PostgreSQL port on the server. I assume then, that the firewall is
the endpoint of the tunnel?

Is there any reason that you don't just forward a port on the firewall
to the PG server, change the 77.77.77.77 line to a hostssl, and enable
SSL in pgAdmin, thus eliminating the need to use pagent etc?

Regards, Dave
