64.2. Built-in Operator Classes

The core PostgreSQL distribution includes the GiST operator classes shown in Table 62.1. (Some of the optional modules described in Appendix F provide additional GiST operator classes.)

Table 62.1. Built-in GiST Operator Classes

Name	Indexed Data Type	Indexable Operators	Ordering Operators
box_ops	box	&& &> &< &<| >> << <<| <@ @> @ |&> |>> ~ ~=
circle_ops	circle	&& &> &< &<| >> << <<| <@ @> @ |&> |>> ~ ~=	<->
inet_ops	inet, cidr	&& >> >>= > >= <> << <<= < <= =

poly_ops	polygon	&& &> &< &<| >> << <<| <@ @> @ |&> |>> ~ ~=	<->
range_ops	any range type	&& &> &< >> << <@ -|- = @> @>
tsquery_ops	tsquery	<@ @>

For historical reasons, the inet_ops operator class is not the default class for types inet and cidr. To use it, mention the class name in CREATE INDEX, for example

CREATE INDEX ON my_table USING GIST (my_inet_column inet_ops);
