Actually, upon looking closely at the toast code, it already does the
right thing when there's no toast table. Good on someone for getting
that right. But we still need to think about whether it's sane for
CREATE/ALTER TABLE to condition the create-a-toast-table decision on
a parameter that may now be changeable.
