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.
