Вопрос

Я использую ключевое слово DEFAULT, предполагается, что это следующий идентификатор, однако, как видите, это неправильно. Я использую PostgreSQL 10.4. Я как-то обнаружил, что extval('*_id_seq'::regclass) не определено. Я использую доктрину для определения структуры базы данных выше, как сказано в документе стратегии генерации идентификаторов.
