title: Delete empty rows
body: <p>I use PostgreSQL database and in one table I have the datetime column <strong>edit_user</strong>. Some rows are blank, and these rows I would like to delete.</p>
  
  <p>I tried</p>
  
  <pre><code>DELETE FROM table WHERE edit_user="";
  </code></pre>
  
  <p>but I got the error</p>
  
  <blockquote>
    <p>LINE 1: delete from table where edit_user="";</p>
  </blockquote>
  
  <p>Also, I thought in the column as a blank value could be <strong>0000-00-00</strong>, but there isn't.</p>
  
  <p>How I should execute this command correctly?</p>
