title: Revoke particular columns in postgresql
body: <p>I've tried using the documentation <a href="https://www.postgresql.org/docs/8.4/static/sql-revoke.html" rel="noreferrer">here</a> but doesn't seem to help. If you can please give me an example.</p>
  
  <pre><code>revoke select (column1, column2) on table from specific_user
  </code></pre>
  
  <p>hasn't worked.</p>
  
  <pre><code>Access privileges
   Schema | Name  | Type  |     Access privileges     | Column privileges | Policies 
  --------+-------+-------+---------------------------+-------------------+----------
   public | users | table | himanshu=arwdDxt/himanshu+|                   | 
          |       |       | reports_user=r/himanshu   |                   |
