Can you elaborate on why you think that? I mean, to me, that's almost
equivalent to removing autovacuum_vacuum_scale_factor entirely,
because only for very small tables will that calculation produce a
value lower than 500k.
We might need to try to figure out some test cases here. My intuition
is that this is going to vacuum large tables insanely aggressively.
