*untested*:

create rule checks_d0 as
	on delete to checks
		do delete from checkitems, checks
			where checkitems.ckid = checks.ckid;

|  add_missing_from is now false by default (Neil)

| By default, we now generate an error if a table is used in a query
| without a FROM reference. The old behavior is still available, but the
| parameter must be set to 'true' to obtain it.
