# DROP OPERATOR CLASS

## Name

DROP OPERATOR CLASS -- remove an operator class

## Synopsis

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

## Description

`DROP OPERATOR CLASS` 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.

## 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.
