A JSON wrapper type for JSONB data obtained from the database.
 The wrapper represents JSONB data() in serialised string form. A CAST(NULL AS JSONB) value is represented by a null reference of type JSONB, not as data() == null. This is
consistent with jOOQ's general way of returning NULL from Result and Record methods. /**
