title: pgAdmin and PostgreSQL: can't connect to server
body: <p>I just installed PostgreSQL on Snow Leopard and can't connect to the database server via pgAdmin 3.</p>
  
  <p>I'm on my local machine, however I keep getting this error: </p>
  
  <p><code>Could not connect to server: connection refused. Is the server running on host "localhost" (127.0.0.1) and accepting TCP/IP connections on port 5423?</code></p>
  
  <p>I'm a bit of a noob when it comes to Postgres, so I'm not really sure what the problem is.</p>
  
  <p>I can, however, log in through the command line, via <code>psql -U postgres</code>, and start and stop the server successfully.</p>
  
  <p>Any help would be much appreciated.</p>
