pg_upgrade --copy-file-range pushed.  The only change I made was to
remove the EINTR retry condition which was subtly wrong and actually
not needed here AFAICS.  (Erm, maybe I did have an unexpressed qualm
about some bug reports unfolding around that time about corruption
linked to copy_file_range that might have spooked me but those seem to
have been addressed.)

I'll also go and rebase CREATE DATABASE ... STRATEGY=file_clone[1].
