The core Postgres Pro 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.
