The default value of join_collapse_limit was 20. When this value is set and the query contains about 20 joins (see added test), Postgres query optimizer cannot build a plan during hours and consumes a lot of memory, because the planner checks a lot of possible ways to join the tables. When join_collapse_limit is 8, the query plan is built in reasonable time. -- This is an automated message from the Apache Git Service.
