And even better, in the first comment to the blog post, I was advised about the 
SETVAL() function which does exactly what I wanted in the first place.

CREATE SEQUENCE persons_person_id_seq;
SELECT SETVAL('persons_person_id_seq', MAX(person_id)) FROM persons;
ALTER TABLE persons ALTER COLUMN person_id SET DEFAULT 
NEXTVAL('persons_person_id_seq');
ALTER SEQUENCE persons_person_id_seq OWNED BY persons.person_id;
