title: switching from MySQL to PostgreSQL for Ruby on Rails for the sake of Heroku
body: <p>I'm trying to push a brand new Ruby on Rails app to Heroku. Currently, it sits on MySQL. It looks like Heroku doesn't really support MySQL and so we are considering using PostgreSQL, which they DO support.</p>
  
  <p>How difficult should I expect this to be? What do I need to do to make this happen?</p>
  
  <p>Again, please note that my DB as of right now (both development &amp; production) are completely empty.</p>
