DROP OPERATOR CLASS

Removes an operator class.

Synopsis

DROP OPERATOR CLASS [IF EXISTS] <name> USING <index_method> [CASCADE | RESTRICT]

Description

DROP OPERATOR drops an existing operator class. To execute this command you must be the owner of the operator class.

Parameters

IF EXISTS
Do not throw an error if the operator class does not exist. A notice is issued in this case.

<name>
The name (optionally schema-qualified) of an existing operator class.

<index_method>
The name of the index access method the operator class is for.

CASCADE
Automatically drop objects that depend on the operator class.

RESTRICT
Refuse to drop the operator class if any objects depend on it. This is the default.

Notes

This command will not succeed if there are any existing indexes that use the operator class. Add CASCADE to drop such indexes along with the operator class.

Examples

Remove the B-tree operator class widget_ops:

DROP OPERATOR CLASS widget_ops USING btree;

This command will not succeed if there are any existing indexes that use the operator class. Add CASCADE to drop such indexes along with the operator class.

Compatibility

There is no DROP OPERATOR CLASS statement in the SQL standard.
