So this proposal (probably along with a higher default threshold than
500000, but IMO less than what Robert and Nathan suggested) sounds like
a stop forward to me. DBAs can set the threshold lower if they want, or
maybe we can just turn it off by default if we cannot agree on a sane
default, but I think this (using the simplified formula from Nathan) is
a good approach that takes some pain away from autovacuum tuning and
reserves that for the really difficult cases.
+1 to the above
Although I don't think 500000 is necessarily too small. In my view,
having autovac run very quickly, even if more frequently, provides an
overall better user experience.
