Get or Create средствами базы данных

У Haki Benita в блоге нашел статью про реализацию функции get_or_create средствами PostgreSQL — How to Get or Create in PostgreSQL: and why it is so easy to get wrong
Отличная статья, мне нравится, что автор использует пошаговый подход и объясняет на каждом этапе какую проблему решает. На первый взгляд может показаться, что нет никаких проблем реализовать Get or Create, но дьявол в мелочах. Рекомендую к прочтению, есть вероятность такой вопрос встретить в будущем на собеседованиях.
