It's not:

SELECT COUNT(*)
FROM "user"
INNER JOIN "house"
ON ("user"."house_id" = "house"."id")
LEFT OUTER JOIN "district"
ON ("house"."district_id" = "district"."id")
WHERE ("user"."status" = 0
AND ("district"."update_status" = 2
OR "district"."update_status" = 3 )
AND ("user"."valid" = 1
OR "user"."valid" = 3 )
AND "district"."is_test" = false );

However, since the anonymization above doesn't quite match that used in
the EXPLAIN plan, I'm not sure what you'll get out of it. And yes, we
know that the outer join is being invalidated.
