Maybe that's worthwhile if we were actually thinking of adding any
non-base 2 units in the future, but if we're not, perhaps it's better
just to have the smaller alias array which for Peter's needs will just
require 1 element + the NULL one instead of 6 + NULL.

In any case, I'm not really sure I see what the path forward would be
to add something like base-10 units would be for pg_size_bytes(). If
we were to change MB to mean 10^6 rather than 2^20 I think many people
would get upset.
