  <p>When I open page with info</p>

  </code></pre>
  <p>Can somebody help please.</p>
  <p>UPDATE</p>
  <p>I think my postgres waiting for date in quotes, like:</p>
  <pre><code>AND &quot;webapp_tickerdata&quot;.&quot;date&quot; &gt;= '2021-01-09'
  </code></pre>
  <p>I'd tried it directly , just select with such params and it works.
  Maybe I need to change settings in postgress?</p>
