I think this sort of reference requirement is meant by the SQL keyword
PENDANT. Not sure what PENDANT ON DELETE CASCADE then is supposed to do,
but removing parents that became childless would be one plausible
interpretation.

PENDANT is not yet implemented in PostgreSQL.

And please, John, can you stop sending your plain text messages as
multipart mime encoded?
