I think we don't want
https://www.postgresql.org/docs/current/auth-radius.html
to become 404, so I'd advocate keeping a short section with that
SGML ID that says we no longer support RADIUS directly and
gives a pointer to the wiki page.  It probably doesn't belong
exactly where it is today in the TOC, though, but shoved off
in a corner somewhere.
