Is it difficult to add parameter like force-dead-rows-removal that we send to the vacuum job that will remove this rows like this ?
I'm still not sure what the ask here is - complete literal removal of the dead rows? That's not how PG works. I'm wondering if we are not in an XY problem. Your queries are slow, and you think it's because of autovacuum's output re dead rows. But let's take a step back and look at the actual queries being run that are slowing down. Perhaps there are other solutions: less indexing, more freezing, smarter updates, different partitioning, tweaking fillfactor, etc. etc. There are lots of things we can try that will be orders of magnitude simpler than trying to redesign MVCC/vacuuming. :)
