title: Heroku app writing to wrong database
body: <p>I created a fork from my production app on Heroku by running this command from their docs: </p>
  
  <p><code>heroku fork --from prod --to stage</code></p>
  
  <p>After experiencing a bunch of issues, I realized the new staging fork is writing to my production database.</p>
  
  <p>Why would it do this by default, and how do I make it use it's own database?</p>
  
  <p>Edit: What makes this even more odd is that when I run <code>heroku pg:info --app stage</code>, it shows <code>Add-on</code> points to the correct DB for stage.  So the DB add-on is correct, but it's writing to the other app's DB.</p>
