Is this code that Ingres uses internally?  Or for the user's use?  If
the former, a lot of RDBMS do similar things basically as a way of
limiting dependencies, ensuring portability, etc.  I think of that as
a special case (it always reminds me of writing a compiler in its own
language) that doesn't affect the user's development of a database
schema.
