The functions in fd.c aren't linked to initdb, so it's a challenge to
share that code (I remember now: that's why I didn't use pg_flush_data
originally). I don't see a clean way to resolve that, do you?

Also, it seems that sync_file_range() doesn't help with creating a
database much (on my machine), so it doesn't seem important to use it
there.

Right now I'm inclined to leave the patch as-is.
