Great, it sounds like we have a plan. I think the wiki might be a
good place for that documentation. The details are likely to change,
and I wouldn't want to have to maintain that information in-tree, so I
created some PAM how-to documentation at
https://wiki.postgresql.org/wiki/RADIUS after testing on Debian and
FreeBSD. We could point to that from the 19 release notes and in the
deprecation notice added to the documentation for 14-18, calling it
"community-maintained guidance on migration to supported
configurations". Do we need to keep any trace of this in the 19 docs,
and if so, where? A new tombstone section?
