# 58.2. Built-in Operator Classes

The core PostgreSQL distribution includes the GIN operator classes shown in Table 58-1. (Some of the optional modules described in Appendix F provide additional GIN operator classes.)

Table 58-1. Built-in GIN Operator Classes

Name | Indexed Data Type | Indexable Operators

`_cidr_ops` | `cidr[]` | `&&` `<@` `=` `@>`
`_date_ops` | `date[]` | `&&` `<@` `=` `@>`
`_float4_ops` | `float4[]` | `&&` `<@` `=` `@>`
`_float8_ops` | `float8[]` | `&&` `<@` `=` `@>`
`_inet_ops` | `inet[]` | `&&` `<@` `=` `@>`

`_int4_ops` | `integer[]` | `&&` `<@` `=` `@>`
`_int8_ops` | `bigint[]` | `&&` `<@` `=` `@>`
`_interval_ops` | `interval[]` | `&&` `<@` `=` `@>`
`_macaddr_ops` | `macaddr[]` | `&&` `<@` `=` `@>`
`_money_ops` | `money[]` | `&&` `<@` `=` `@>`
`_name_ops` | `name[]` | `&&` `<@` `=` `@>`
`_numeric_ops` | `numeric[]` | `&&` `<@` `=` `@>`
`_oid_ops` | `oid[]` | `&&` `<@` `=` `@>`
`_oidvector_ops` | `oidvector[]` | `&&` `<@` `=` `@>`
`_reltime_ops` | `reltime[]` | `&&` `<@` `=` `@>`
`_text_ops` | `text[]` | `&&` `<@` `=` `@>`
`_time_ops` | `time[]` | `&&` `<@` `=` `@>`
`_timestamp_ops` | `timestamp[]` | `&&` `<@` `=` `@>`
`_timestamptz_ops` | `timestamp with time zone[]` | `&&` `<@` `=` `@>`
`_timetz_ops` | `time with time zone[]` | `&&` `<@` `=` `@>`
`_tinterval_ops` | `tinterval[]` | `&&` `<@` `=` `@>`
`_varbit_ops` | `bit varying[]` | `&&` `<@` `=` `@>`
`_varchar_ops` | `character varying[]` | `&&` `<@` `=` `@>`
`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.
