How to start working with upgraded version of D2000?

I just upgraded my D2000 system and I have problems with Demo application. I need to login to PostgreSQL Server, but I need a password for database user. I really don´t remember, if I have ever create any account. Is there any other way how to run Demo without login into PostgreSQL Server? Or what should I do next? Thanks for answer!

Edit pg_hba.conf, setting the auth mode to trust instead of the default md5
In the Services control panel restart the PostgreSQL service
Connect with psql or PgAdmin or whatever
ALTER USER postgres PASSWORD 'mynewpassword';
Edit pg_hba.conf again and set the auth mode back to md5
Restart PostgreSQL again and vuala :)

I´m going to try it, thanks!

Let me know if it helped …
