I think we also need something like your previously-posted

multixact-truncate-race.patch as a follow-on.  I'm not at all
convinced that there is no possibility of truncating new data as
things stand; and even if that is true now, it seems terribly
fragile.  (Only mentioning it because it wasn't noted in the commit
message.)
