title: How to check if a value in a numeric field is an integer?
body: <p>I have a numeric column in Postgresql with these values:</p>
  
  <pre><code>1.0
  3.5
  1.5
  4.0
  </code></pre>
  
  <p>I want to write a query which will give me all rows that aren't integer.
  Meaning I want to get:</p>
  
  <pre><code>3.5
  1.5
  </code></pre>
