Query - Mailing list pgsql-general

I have recently changed from HEM2 to PT4, during the changeover i uninstalled Postgres and HM2, i then went on to install PT4 and postgres 8.4.

When i know run PT4 and try and install Postgres from there it shows me the top two below images.

When i try and connect to postgress from PT4 it shows me the middle below image.

I also tried looking on forums to solve this, but with no luck - Can the bottom photo show you anything you need to know?

Please advise and help.

Many thanks
