No. Serial has a minval of 1, correct. However, when the minval is one
and nextval is one, the nextval is...one.
In other words, a newly created serial sequence will return 1 the first
time it is called and 2 the second time. (The case is special when
creating sequences for use
as a serial because you, IIRC, must call nextval() once to make the
nextval one. In other words, the first two values out of a newly created
non-serial sequence with minval=1 are one.)
