63.2. Built-in Operator Classes
The core Postgres Pro distribution includes the GIN operator classes shown in Table 63.1. (Some of the optional modules described in Appendix F provide additional GIN operator classes.)
Table 63.1. 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.
