Hi,
In dc6acfd910b8, I added some counters to track and log in
autovacuum/vacuum output the number of pages newly set
all-visible/frozen. Taking another look at the code recently, I
realized the conditions for setting the counters could be simplified
because of what we know to be true about the state of the heap page
and VM at the time we are doing the counting.
Further explanation is in the attached patch. This code is only in 18/master.
- Melanie
