Responding to Tom's email about guc.c changes [1], I was looking at
MemoryContextContains(). Unless I am missing something, the patch omitted
adjusting that? We'll probably always return false right now.

Probably should have something that tests that MemoryContextContains() works
at least to some degree. Perhaps a test in regress.c?
