-- ВПР время выполнения резко увеличивается при переносе или просто добавлении agreement_is_actual AND в CTE, необъяснимо. Индекс не помогает. Добавление в общее условие where может очень сильно ускорить. Добавление в несколько мест может сильно ускорить
-- ага. тут есть ошибка - возвращается разное количество строк. Что говорит о существенной ошибке в запросе
