If it doesn't, then it's broken. A general rule of the system is that
structures being allocated for return to a routine's caller must be
allocated in the caller's CurrentMemoryContext. The only exceptions are
for cases where the routine in question is taking responsibility for the
long-term management of the object (for example, a syscache) --- in
which case, it isn't your problem.
