Re: EXPLAIN BUFFERS and I/O timing accounting questions

Also, I noticed that in this plan, the root (again, an Aggregate) has 0
Temp Read Blocks, but two of its children (two of the ModifyTable nodes)
have non-zero Temp Read Blocks. Again, this contradicts the documentation,
as these costs are stated to be cumulative. Any ideas?

Thanks,
