Столкнулся с проблемой. Слишком много времени, полсекунды, постгрес тратит на планирование запроса. План выбирает правильный, к этому претензий нет. Исполняется запрос тоже быстро, за сотые доли секунды. На сервере Postgres 9.5.

Пробовал крутить настройки geqo, from_collapse_limit, join_collapse_limit, переформулировать запрос. Не помогает.

Как можно ускорить планирование этого запроса?

Не хотелось бы использовать prepared statements, потому что работаем через Django ORM.

Поможет ли здесь pg_pathman? Но check contraints в партиционировании не используем.

PS: При изменении условий теста замедление исчезает полностью или сокращается. Подробности ниже.

LeXa NalBat,

Партиционирование, однако.

Насчёт pathman-а -- он может помочь, ибо ради этого его и делали. Но:
после анонса я спрашивал, можно ли его прикрутить к существующим партициям. Было нельзя, как сейчас -- не знаю.

был баг, который отдавал неверные данные (в фейсбуке пробегал). надо убедиться, что он закрыт. Не знаю, есть ли у проекта трэкер какой.

Legushka,

Да, классно, планирование чуть измененного вашего запроса работает быстро. (Нужно сначала выбрать из time, затем из usage, затем из остальных.)

Попробуй переписать запрос как (разделив план на 2 независимых блока

    inner join dim5 on (usage.dim5_id = dim5.id)

;



Если всеравно медленно - посмотри сколько времени планируется запрос в WITH блоке.
