title: Error installing PostgreSQL via Homebrew on Mac
body: <p>When installing PostgreSQL via Homebrew on Mac (OSX 10.11.6) I get the following errors:</p>
  
  <pre class="lang-none prettyprint-override"><code>Error: The `brew link` step did not complete successfully The formula
    built, but is not symlinked into /usr/local
  </code></pre>
  
  <p>and</p>
  
  <pre class="lang-none prettyprint-override"><code>initdb: file "/usr/local/share/postgresql/postgres.bki" does not exist
    This might mean you have a corrupted installation or identified the 
    wrong directory with the invocation option -L.
  </code></pre>
  
  <p>The <code>/postgresql</code> folder doesn't exist.</p>
  
  <p>Not sure if it's relevant, but I already have OpenSSL 1.0.2o_2 and Readline 7.0.5 installed via Homebrew.</p>
  
  <p>Does anyone know why this error occurs and how I can solve it?</p>
