Description:        buggy install + no manual support (add)
Details:

Installation completes w/o exceptions when i check off "initial database"
option during install, no port could be selected and it ends up in selecting
port from previous installation in pre-deleted configuration file (probably
from old install registry entry) .... but still don't want to createdb
(firewall was down, and in all previous cases as well, even it's the same
when it's on)

what's behind this kind of failure, service starts and stops ok, path isn't,
-u/-p switches doesn't help it regularly connects but throws an exception
