I am not sure if I really understood the intention of the question correctly,
but if the question was if pg should try to work around misuse of signals, then
my answer would be a definite no.
IMHO, the signal handler should check if the signal was received for good
reasons (as proposed by Noah) and handle it appropriately, but otherwise ignore it.
