A more general solution would be to have a new MemoryContext
implementation that does the same your patch does. Ie. instead of
tracking each allocation, just allocate a big chunk, and have palloc()
return the next n free bytes from it, like a stack. pfree() would
obviously not work, but wholesale MemoryContextDelete of the whole
memory context would.
repalloc() will not work too. Such implementation should have possibility to
debug memory allocation/management by using some kind of red-zones or
CLOBBER_FREED_MEMORY/MEMORY_CONTEXT_CHECKING
