title: How to downgrade Postgres from 9.6 to 9.5
body: <p>I removed my 9.6 postgres.app (removing the application by dragging it to the trash) and downloaded postgres.app.</p>
  
  <p>However, when I did </p>
  
  <pre><code>locate initdb 
  </code></pre>
  
  <p>It still points to the wrong location:</p>
  
  <pre><code>/Applications/Postgres.app/Contents/Versions/9.6/bin/initdb
  /Applications/Postgres.app/Contents/Versions/9.6/share/doc/postgresql/html/app-initdb.html
  /Applications/Postgres.app/Contents/Versions/9.6/share/man/man1/initdb.1
  </code></pre>
  
  <p>What would be the most efficient way to resolve this problem?</p>
