There isn't any of that stuff that's *in* TopMemoryContext. Whether the
hash table contexts are children of TopMemoryContext or
CacheMemoryContext would be important if we were ever going to reset
either, but we aren't. The main point in my mind is that it be possible
to tell from a memory stats dump how much is being used for what, and we
do have that.
