It's difficult to provide evidence for the existence of a perception among users when it's a perception that a quasi-reasonable limitation exists. The fact that jsonb_path_ops can make indexing complex jsonb documents practical is fairly novel, so I'm not surprised that users seem to imagine that containment does not work in a nested fashion. "Existence" (the ? operator) actually has this limitation. -- Peter Geoghegan -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
