I believe this is a variant of the existing open issue about the outer-join-Vars stuff: https://www.postgresql.org/message-id/flat/0b819232-4b50-f245-1c7d-c8c61bf41827%40postgrespro.ru although perhaps different in detail --- EXPLAIN shows that the join condition has gone missing completely, rather than just being put at the wrong join level. Possibly related to the join removal that happened to pg_db_role_setting? I've been incredibly distracted by $real-life over the past few weeks, but am hoping to get the outer-join-Vars issues resolved in the next day or two. regards, tom lane
