Heroku creates a database for each application deployed to it (no need to run `heroku rake db:create`. Here are the commands you should be using to deploy a Rails application to Heroku:

```
git init
git add .
git commit -m "initial import"
heroku create
git push heroku master
heroku rake db:migrate
heroku open

```
I believe Heroku creates a new database.yml for you on deploy if you have no production according to the [Docs](http://groups.google.com/group/heroku/browse_thread/thread/cfa3ad5263a9e967?pli=1).
