The problem with using just major version there is that then we are
*wiring into the on-disk representation* the assumption that pg_migrator
only goes from one major version to the next. I agree that we're not
likely to start supporting cross-alpha-version migration any time soon,
but I don't think it's wise to foreclose the possibility of ever doing
it.
