Agreed. I suspect the most realistic way to address most of the
objections in a short amount of time would be to:
1. rip out the local map
2. restore hio.c to only checking the last block in the relation if
there is no FSM (and lower the threshold to reduce wasted space)
3. reduce calls to smgr_exists()
Thoughts?
