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.
