Uh, the last sentence in that section says:
The sequence to be operated on by a sequence function is specified by a
regclass argument, which is simply the OID of the sequence in the
pg_class system catalog. You do not have to look up the OID by hand,
however, since the regclass data type's input converter will do the work
for you. See Section 8.19 for details.
