title: Change from SQLite to PostgreSQL in a fresh Rails project
body: <p>I have a rails app that's databases are in SQLite (The dev and production). Since I am moving to heroku, I want to convert my database to PostgreSQL.</p>
  
  <p>Anyways, I heard that the local, development, database does not need to be changed from SQLite, so I don't need to change that, however, how do I go about changing the production environment from SQLite to PostgreSQL?</p>
  
  <p>Has anyone ever done this before and can help?</p>
  
  <p>P.S. I'm not sure what exactly this process is called, but I've heard about migrating the database from SQLite to PostgreSQL, is that what needs to be done?</p>
