title: Is there any way to restart postgres on Heroku?
body: <p>I deploy a Rails app using Unicorn. After every deployment and after every tweak I do to the <code>DB_POOL</code> I see postgres still hold some connections as idle and new changes are very inconsistently making me wondering If is restarting at all the service after every pool change. </p>
  
  <p>I haven't found any documentation regarding this. Is there any similar command to pg_ctl on Heroku?</p>
