Having several clusters (installations) of PostgreSQL on the same
machine need different port numbers. The default ist 5432, usually
further installations use 5433, 5434 and so on.
If you want to test the connectivity of your server, it's best *not* to
use any third party tools (pgAdmin is one of them), but psql, which is
part of the PostgreSQL software. It tends to give better error messages.
And of course, have a look at the log files.
Regards,
Holger
