title: PostgreSQL - IN vs ANY
body: <p>I have tried both:</p>
  <ol>
  <li><p><em>smthng <strong><code>= ANY</code></strong> <code>(select id from exmplTable)</code></em></p>
  </li>
  <li><p><em>smthng <strong><code>IN</code></strong> <code>(select id from exmplTable)</code></em></p>
  </li>
  </ol>
  <p>and I am getting the same results for my data.</p>
  <p>Is there any difference for the two expressions?</p>
