The core PostgreSQL distribution includes the GIN operator classes shown in Table 68.1. (Some of the optional modules described in Appendix F provide additional GIN operator classes.)

Of the two operator classes for type jsonb, jsonb_ops
is the default. jsonb_path_ops supports fewer operators but
offers better performance for those operators.
