That seems overkill.
The problem is likely that the "old tuples" are in some database not
being vacuumed. template1 is a likely candidate; do a plain VACUUM on
that and the message may go away.
It can be *possible* for the issue to be with template0, if it had at
some point been open for modification. If that is the case, it is a
good idea to:
- Unlock template0 (via table pg_database)
- Run VACUUM FREEZE on template0
- Relock it
