56.2. Built-in Operator Classes

The corePostgreSQL distribution includes theGiST operator classes shown inTable 56-1. (Some of the optional modules described inAppendix F provide additionalGiST operator classes.)

For historical reasons, theinet_ops operator class is not the default class for typesinet andcidr. To use it, mention the class name inCREATE INDEX, for example

CREATE INDEX ON my_table USING gist (my_inet_column inet_ops);
