title: Is a new database created when a Heroku application is forked?
body: <p>I forked a heroku application (on the cli, using <code>heroku fork</code>). However, when I checked the fork application's config vars, the DATABASE_URL that it's set to is exactly the same as in the original application which I forked.</p>
  
  <p>Can I push database schema changes to the new fork without affecting the original application? Or is there a need to fork the database as well?</p>
