The SERIAL datatype (e.g., CREATE TABLE foo(foo_id SERIAL) )is a
shorthand for something like
CREATE SEQUENCE foo_id_seq;
CREATE TABLE foo (foo_id integer default nextval('foo_id_seq') );

If you want it to specify the start value, you'll need to either use
CREATE SEQUENCE first and then create the table with the appropriate
default, or use ALTER SEQUENCE after creating the table.
