66.2. Built-in Operator Classes

The core PostgreSQL distribution includes the GIN operator classes shown in Table 66.1. (Some of the optional modules described in Appendix F provide additional GIN operator classes.)

Table 66.1. Built-in GIN Operator Classes

Name Indexed Data Type Indexable Operators
array_ops anyarray && <@ = @>
jsonb_ops jsonb ? ?& ?| @> @? @@
jsonb_path_ops jsonb @> @? @@
tsvector_ops tsvector @@ @@@

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. See Section 8.14.4 for details.
