title: How to access postgresql.conf file of postgresql deployment on Heroku
body: <p>I have a Django app hosted on Heroku, with a postgresql DB, on a <em>Standard 0</em> plan. I want to access and read the <code>postgresql.conf</code> file for this particular app (to ascertain/edit the settings). Can anyone guide me how to do that? </p>
  
  <p><em>Note: I can't do that via the Heroku dashboard, and I don't know how to access the app's file structure over the Ubuntu commandline.</em></p>
