I think the ideas are quite different. I see in that patch you're
raising an ERROR if the memory usage goes over some threshold. What I
had in mind was adding lightweight opt-in infrastructure to allow code
to quickly check how much memory is being consumed by a MemoryContext
and all of its child contexts.
