Still, they do admit the possibility of insertable_into being different
from is_updatable. So I'm pretty happy with what we've got, at least
on the relation level. Columns seem a bit more debatable; though I
continue to think that an is_updatable column in a not-is_updatable
table isn't contemplated by the spec.
