SERIAL is just a convenient way of creating an INTEGER column with
a default value. If you provide a value for that column then the
default isn't used, so the INSERT never calls nextval() to increment
the sequence.
If you need to set some of the SERIAL column's values explicitly,
e.g., when importing data, then you can use ALTER SEQUENCE or
setval() when you're finished to change the sequence's value.
