Description:

Hi.
On my old installation with pg 8.4 this query executes about 3 seconds, but
on 9.5 it never ends and cpu usage rises up to 100% by postgres process.

Problem is here near RIGHT OUTER JOIN
Query works with LEFT OUTER JOIN and other inner joins

If I will create 2 views from "AS info" (about 2k rows) and "AS all_res"
(about 200 rows) tables it will not fix anything. BTW separate "AS info"
query executes less than in 3 sec, "AS all_res" less than 1 sec.

I have solved this problem by using WITH info, all_res queries. Now it works
pretty fast.
