pg_control would not be the right place for that structure. It's
intended to be fixed-size (it's just a serialized C structure) and it
should be smaller than a sector so that it doesn't suffer from torn

Not a bad approach overall, but requires some kind of new structure. And
that increases the risk that it doesn't make 9.3.

Right now, I'm honestly just trying to get the simplest approach that
doesn't restrict these kinds of ideas if we want to do them later.
