No, I was thinking of some sort of memory allocation stats collection
that doesn't depend on DTrace.  It's amazing to me that we've never
gone back and improved on the original quick-and-dirty
MemoryContextStats mechanism.  I certainly find myself using that a
lot for issues like tracking down memory leaks.  While palloc has a lot
of advantages, the fact that you can't easily plug in a debug-friendly
substitute malloc package is not one of them :-(
