The database has not been issuing VACUUMs on some or all of the relations, so the system needs to issue "anti-transactional wraparound" VACUUMs.
Thanks, once I logged in with another user I saw there's one relation that is being vacuumed to prevent tx wraparound. The sheer number of those log entries made it seem like the autovacuum is in a loop.
