That seems like an odd way to approach this. Why not just remove the
reset of _SPI_stack and _SPI_stack_depth, so as to subtract code rather
than adding it --- that is, make it actually work like you mistakenly
thought it did? If we're going to keep the stack in TopMemoryContext,
there's no need to thrash it on every transaction.
