37.14. column_privileges
  The view
  
   column_privileges
  
  identifies all
   privileges granted on columns to a currently enabled role or by a
   currently enabled role.  There is one row for each combination of
   column, grantor, and grantee.
 
  If a privilege has been granted on an entire table, it will show up in
   this view as a grant for each column, but only for the
   privilege types where column granularity is possible:
