This definition is OK with me ... so long as it still includes the
phrase "an error occurs if no nextval or setval has occurred in the
current session". However it seemed that a number of people asking
for the feature wanted some-random-default to be returned instead.
Another question is why should setval affect the result? I don't
see the use-case for that offhand.
