role_column_grants
   The view role_column_grants identifies all
   privileges granted on columns where the grantor or grantee is a
   currently enabled role.  Further information can be found under
   column_privileges.  The only effective
   difference between this view
   and column_privileges is that this view omits
   columns that have been made accessible to the current user by way
   of a grant to PUBLIC.
