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

       In the SQL standard, WITH HIERARCHY OPTION
       is a separate (sub-)privilege allowing certain operations on
       table inheritance hierarchies.  In PostgreSQL, this is included
       in the SELECT privilege, so this column
       shows YES if the privilege
       is SELECT, else NO.
