title: How to delete a column from parent table and propagate this to all child tables
body: <p>Can someone help me with this? I have a set of tables that are inherited from a single parent table (now all these tables are containing data).</p>
  
  <p>I need to drop a particular column from the parent table and the same column from all inherited tables should be dropped automatically. Is this possible? </p>
  
  <p>When I tried this, only the parent table column was dropped. I tried cascade option also in the alter table, but no result.</p>
  
  <p>I am using postgreSql 8.3</p>
