Setting up Ruby on Rails port and Openstreetmap Database

Hi,

I am following the introductions on http://wiki.openstreetmap.org/wiki/The_Rails_Port to setup my own openstreetmap environment on a local Ubuntu machine. But now I am stuck at the point where I have to copy database.yml to the appropriate location. Can someone tell me where to copy that file? I am using Postgres Database.

Regards

Michael
