## 68.2. Built-in Operator Classes

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.)

Table 68.1. Built-in GIN Operator Classes

Name | Indexable Operators
--- | ---
`array_ops` | `&& (anyarray,anyarray)`
`@> (anyarray,anyarray)`
`<@ (anyarray,anyarray)`
`= (anyarray,anyarray)`
`jsonb_ops` | `@> (jsonb,jsonb)`
`@? (jsonb,jsonpath)`
`@@ (jsonb,jsonpath)`
`? (jsonb,text)`
`?| (jsonb,text[])`
`?& (jsonb,text[])`
`jsonb_path_ops` | `@> (jsonb,jsonb)`
`@? (jsonb,jsonpath)`
`@@ (jsonb,jsonpath)`
`tsvector_ops` | `@@ (tsvector,tsquery)`
`@@@ (tsvector,tsquery)`

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.
