title: PG::ConnectionBad fe_sendauth: no password supplied
body: <p>Disclaimer: I'm very new to programming in general, so please excuse my sizeable ignorance.
  I'm trying to run an application I've written in rails, but when I do, I get the error "fe_sendauth: no password supplied".<br>
  Here's my database.yml, I have a feeling it's something in here.  </p>
  
  <pre><code>default: &amp;default
      adapter: postgresql
      pool: 5
      timeout: 5000
  
  development:
    &lt;&lt;: *default
      database: url-shortener_development
  
  test:
    &lt;&lt;: *default
    database: url-shortener_test
  
  production:
    &lt;&lt;: *default
    database: url-shortener_production
    username:
    password:
  </code></pre>
