Uh, the commit is:
commit f78ca6f3ebb
Author: Thomas Munro <tmunro@postgresql.org>
Date: Tue Apr 8 20:52:47 2025 +1200
Introduce file_copy_method setting.
It can be set to either COPY (the default) or CLONE if the system
supports it. CLONE causes callers of copydir(), currently CREATE
DATABASE ... STRATEGY=FILE_COPY and ALTER DATABASE ... SET TABLESPACE =
..., to use copy_file_range (Linux, FreeBSD) or copyfile (macOS) to copy
files instead of a read-write loop over the contents.
CLONE gives the kernel the opportunity to share block ranges on
copy-on-write file systems and push copying down to storage on others,
depending on configuration. On some systems CLONE can be used to clone
large databases quickly with CREATE DATABASE ... TEMPLATE=source
STRATEGY=FILE_COPY.
Other operating systems could be supported; patches welcome.

Uh, does this mean I should add Thomas Munro before or after your name,
or remove your name and list only Thomas Munro?
