That's a massive project. Which is why I'm explicitly *not* suggesting
that. What I instead suggest is a separate threshhold after which vacuum
isn't going to abort automaticlaly after a lock conflict. So after that
threshold just behave like anti wraparound vacuum already does.
Maybe autovacuum_vacuum/analyze_force_threshold or similar. If set to
zero, the default, that behaviour is disabled. If set to a positive
value it's an absolute one, if negative it's a factor of the normal
autovacuum_vacuum/analyze_threshold.
