One other possiblity would be to push a version of pg_surgery that is
compatible with the back-branches somewhere external (e.g. either
git.postgresql.org and/or Github), so that it can be picked up by
distributions and/or individual users in need.

did not read the thread in detail but I was under the assumption it is a
client program?
