Hi Sayan,

I have CCed the pgsql-admin list here, in the hope that somebody might
reply (full question below).  I think the answer to your question is to
use a window function.

Please make sure to always write to pgsql-admin@postgresql.org, not the
"-owner" address.  Otherwise, your message never reaches the list.
