  <p>Is I have installed this </p>
  
  <pre><code>pip install psycopg2-binary
  </code></pre>
  
  <p>and this </p>
  
  <pre><code>pip install psycopg2==2.7.4 
  </code></pre>
  
  <p>on my virtualenv, but none of the commands fixed my issue.</p>
  
  <p>I have checked all the postgres setting but I still have the same issue. Is that a problem with my postgres setting or installation issue?? </p>
