I think it's clearer if "min" and "max" are considered adjectives and always
have a subject they modify. Otherwise it's unclear what they refer to.
So "vacuum_freeze_min_age" and "vacuum_freeze_max_age" instead.
That way it's unambiguous which is which. Ie, that it's minimum and maximum
age and not minimum and maximum transaction id which would be the other way
around.
