Peter Eisentraut 3a769d8239 pg_upgrade: Allow use of file cloning ... Add another transfer mode --clone to pg_upgrade (besides the existing --link and the default copy), using special file cloning calls. This makes the file transfer faster and more space efficient, achieving speed similar to --link mode without the associated drawbacks. On Linux, file cloning is supported on Btrfs and XFS (if formatted with reflink support). On macOS, file cloning is supported on APFS.
