Chicken-and-egg problem there: you won't know if there's an endianness
flag to check without having tested pg_control_version.

What would work better is to add some code that checks whether
pg_control_version looks like the byte-swap of a small number,
and prints a suitably modified error message if so.

I would not previously have thought this was worth the trouble,
but given what we now know about Apple's migration process,
it might be worth another half dozen lines of code and a new
error message.

What was that about string freeze ;-) ?
