title: Installed Postgres.app but it won't work
body: <p>I just installed <a href="http://postgresapp.com/" rel="noreferrer">Postgres.app</a> on my Mac but it won't work properly. I finished the installation and the app icon is on the menu bar and it says it is listening on port 5432, however, that is what happens if I try to run it from the command-line:</p>
  
  <pre><code>~ $ psql
  zsh: correct 'psql' to 'sl' [nyae]? n
  zsh: command not found: psql
  </code></pre>
  
  <p>I had previously installed PostgreSQL via Homebrew but removed it before installing Postgres.app. I am running Mac OS X Lion.</p>
  
  <p>I appreciate any help, I really want to have PostgreSQL running on my machine.</p>
