title: remove stop words without stemming in postgresql
body: <p>I want to remove the stop words from my data but I do not want to stem the words since the exact words matters to me. 
  I used this query. </p>
  
  <pre><code>SELECT to_tsvector('english',colName)from tblName order by lower asc;
  </code></pre>
  
  <p>Is there any way that I can remove stopWords without stemming the words?</p>
  
  <p>thanks</p>
