title: pgAdmin III : No servers showing up
body: <p>I've followed many online tutorials on how to install pgAdmin correctly, I've installed and uninstalled it multiple times but whenever install it. It shows Server Groups without any servers in it. </p>
  
  <p>Then when I try and register a new server using <code>localhost</code> for both name and host I get this error:</p>
  
  <pre><code>server doesn't listen
  </code></pre>
  
  <p>Searched for days trying to find a solution for this, any ideas?<img src="https://i.stack.imgur.com/2VCGC.jpg" alt="enter image description here"></p>
