Hi there! In a project I was experimenting with replacing array columns with JSONB columns, to allow a greater flexibility of types.
One thing that I found missing is the "overlap" operator (&&) <https://www.postgresql.org/docs/9.6/static/functions-array.html>. JSONB includes all other operators from arrays, such as containment (@>, <@), comparison (>, >=, <, <=) and inclusion (?) <https://www.postgresql.org/docs/9.6/static/functions-json.html>. The only one missing is the overlap operator (&&). Does anyone know of a technical reason that operator was not included on JSONB? Best regards, Eduardo Felipe. E3C Tecnologia
