Consider following sequence of events:
0. We schedule some buffers for IO
1. We call RelationGetNumberOfBlocks() in callback when current_block == last_exclusive and return InvalidBlockNumber
tosignal EOF
After this:
2. Some page is getting split into new page with number last_exclusive
3. Buffers from IO are returned and vacuumed, but not with number last_exclusive, because it was not scheduled
Maybe I'm missing something...
