Er ... what would you define as "user code"?
The deadman switch is engaged at the point where we create a PGPROC.
Before that, it's entirely impossible to take either LWLocks or
heavyweight locks, which means that practically any access to shared
memory would be illegal anyway. If there's anything very interesting
going on in that stretch, I'd be surprised.
