No, deadlock detection is not optional.

Even if it's not killed, how does it know to decrement the reference
count? You still need a list of all locked tuples *somewhere*. Perhaps
a technique like this would allow the list to not be in shared memory,
which is helpful, but it's far from an ideal solution.
