The bool parameter sets the is_called state bit of the sequence.
Without this you can't restore a sequence to a virgin "never nextval'd"
state.
Actually, none of the sequence-related functions are documented in
what I'd call a proper way. I think there should be a separate section
of the user's guide "Functions and Operators" chapter that describes
them --- not a large section, but a section nonetheless. Any
volunteers to write it?
