title: Heroku pg:backups fails with "an error"
body: <p>This kind of arbitrary failure seems to be part of the Rails app learning curve, so I apologize for such a simpleminded question, but: '<code>heroku pgbackups:capture</code>' is simply...failing. That is, I captured the URL for my Postgresql database on heroku, then pasted it into:</p>
  
  <blockquote>
    <p>% heroku pgbackups:capture postgres://<code>&lt;secret rest of db URL&gt;</code></p>
  </blockquote>
  
  <p>...and get the following response:</p>
  
  <blockquote>
    <p>Database on ec2-50-19-215-116.compute-1.amazonaws.com  ----backup--->  b003</p>
    
    <p>Pending...  \</p>
    
    <p>!    An error occurred and your backup did not finish.</p>
  </blockquote>
  
  <p>Helpful, eh? Any clues how I can suss this out? Thanks for help with a naive question.</p>
