Those are the docs for the current version (v15).

vacuumdb is a client, which can run against older (or newer) servers.

The --force-index-cleanup option was added in v14, and can be used
against servers back to v12.  But the command-line option to the
vacuumdb client doesn't exist before v14 (even though the server-side
supports it).

I don't know.  But this busy mailing list is for development; these
questions would be better addressed to pgsql-user.
