title: pgAdmin III installed after postgres - how do I view/connect to existing databases?
body: <p>I'm so new to this I'm not even sure I know how to ask the question, but hopefully it makes sense:</p>
  
  <p>I installed postgres on OS X Yosemite (following these instructions: <a href="https://gorails.com/setup/osx/10.10-yosemite" rel="nofollow">https://gorails.com/setup/osx/10.10-yosemite</a>) and have made some databases.</p>
  
  <p>Having used Microsoft SQL Server in the past, I wanted a GUI with which to view the databases so I downloaded and installed pgAdmin III (using the first link on <a href="http://www.postgresql.org/download/macosx/" rel="nofollow">http://www.postgresql.org/download/macosx/</a>).  Unfortunately, it seems like pgAdmin III has just installed a new instance of postgres, as it doesn't show any of the databases I made (within Terminal) in the original postgres installation.</p>
  
  <p>Does anyone know how to amend my settings in pgAdmin III so that it just acts as a 'screen' for the existing postgres installation?</p>
