I don't think it was possible at all. Perhaps Previously subscript handling was hard-coded into the server, so that subscripting could only be applied to array types. This change allows subscript notation to be used to extract or assign portions of a value of any type for which the concept makes sense. > JSONB subscripting can be used to extract from and assign to > JSONB documents. Perhaps "extract and assign to portions of JSONB documents" or something like that? regards, tom lane
