It's not clear to me that fiddling with that is useful unless the toast
tuple size also changes; and unfortunately changing that is much harder,
because it's wired into the addressing of toast data. See also these
notes:
* XXX while these can be modified without initdb, some thought needs to be

* changes. Also see LOBLKSIZE in large_object.h, which can *not* be
* changed without initdb.
