title: How to setup new Redshift database with Heroku/Rails 4 app
body: <p>I have been using Heroku-postgres as my database for my rails 4 app deployed to Heroku.</p>
  
  <p>I connect to the DB locally using pgAdmin3, and haven't had any issues.</p>
  
  <p>Now, I want to switch my database to a amazon-redshift instance which has been spun up for me. All I have is a username, password, and the database host name. Where do I store this information within my Rails 4 app so that my app will use this DB instead of the current postgres DB?</p>
