register another instance ?

Hi,

I've installed the binary port of postgres from pgfoundry ( works great 
!!!)

But I have to install a second instance of postgresql on the same server 
for separating between testsystem and production system.



1. when doing a pg_ctl register manually, pgadmin is not able to 
start/stop the service (perhaps a special option ? )

2. Is there a gui-tool / different way to install the service like during 
the installation (win32-installer) ?


best regards

tom
