Dmitry, Alexander: I'm noticing a feature gap for JSONB operators; we have no way to do this:
jsonb_col ? ARRAY['key1','key2','key3'] ... that is, there is no way for us to check for key existence in an indexable fashion. Given that @> already can check the whole path including the value, is there some challenge to stopping just short of the value I'm not seeing? Or is this just a "didn't get to it yet" issue? I'm trying to estimate the difficulty of creating this operator in an extension (obviously we're not doing it for 9.5), and maybe for 9.6. -- Josh Berkus PostgreSQL Experts Inc. http://pgexperts.com -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
