Actually you don't need to create a new user each time you create a new rails app.

All you have to do is create the new application and change the username in your database.yml

development:
  adapter: postgresql
  encoding: unicode
  database: newapp_development
  pool: 5
  username: #your username
  password:
...

than just:

rake db:create:all

On a unix based system:

sudo -u postgres createuser -d -R -P APPNAME
sudo -u postgres createdb -O APPNAME APPNAME

You can create a script and put it somewhere in your $PATH if you can't remember.
