This is actually the way sequences work (ie, it's a feature, not
a bug, heh heh)

currval() gives you the current value of the sequence
*as seen in this session* ... so until you do a setval()
or a nextval() there is no value seen by this session.

nextval()? hmm. well. If the user does not have privelege to
update the sequence, then the call will fail.
