That seems like a tenuous leap. A typical reason for the pipe is to
transfer it to a different machine and that only has to be done once.
But I'm not convinced it's such a great idea either for the reason I
described -- It makes the case where pg_restore has to read through
the whole archive that much harder to explain to users. So I'm not
really going to argue for it too strongly. It's also a fair amount of
extra complexity for not much gain. We would still need the fallback
code anyways.
