Oh, I created (actually, Doctrine created) those with :
CREATE TABLE Article (id INT NOT NULL, name VARCHAR(16) NOT NULL, PRIMARY
KEY(id));
CREATE SEQUENCE Article_id_seq INCREMENT BY 1 MINVALUE 1 START 1;
Instead of :
CREATE SEQUENCE Article_id_seq INCREMENT BY 1 MINVALUE 1 START 1 OWNED BY
Article.id;

I did not knew about "ownership" of sequences, because the id incremented
so I thought the system knew what field to alter through the sequence name.
Thanks for the tip, I'll fork Doctrine to add it if there's no BC break
ripple effect resulting from the change.
Sorry about the bother,
