So, my simple conclusion is that glibc emulation should be about the same as what we're doing now, so there's no reason to avoid it. That means, if posix_fallocate() is present, we should use it, because it's either the same (if emulated in glibc) or significantly faster (if implemented in the kernel).
That's what I'm seeing everywhere too. I'm happy that we've spent enough time chasing after potential issues without finding anything now. Pull out the GUC that was added for default and this is ready to commit.
