I wanted to connect uDig with my PostGIS database to add a new layer.

Host: localhost
port: 5432
user: postgres
password: ***

and then it showed me my databases. I selected one (with 5 tables in it), and wanted the programm to list the tables. But it doesn't show anything.
Looks like by selected database was empty. But it is not.

Is there anyone who can help me? I didn't find anything with google.
