Since postgre now suppport referential integrity and cascading deletes,
wouldn't it make more sense to use that code to manage the relationship
between pg_user and pg_group (and probably a wealth of other system tables),
rather then having to write specific code to manage every relationship
between system tables, or are those types of constraints just not applicable
to system tables?
