  1. Introduce file_copy_method GUC 

    This GUC can be set to either COPY (default) or CLONE (if system
supports it).

If CLONE method is chosen, similar to COPY; but attempting to use
efficient file copying system calls.  The kernel has the opportunity to
share block ranges in copy-on-write file systems, or maybe push down
the copy to network file systems and storage devices.

Currently works on Linux, FreeBSD and macOS.  More systems could be
supported.
