DROP OPERATOR CLASS — remove an operator class
DROP OPERATOR CLASS [ IF EXISTS ]name
USINGindex_method
[ CASCADE | RESTRICT ]
DROP OPERATOR CLASS drops an existing operator class. To execute this command you must be the owner of the operator class.
DROP OPERATOR CLASS does not drop any of the operators
or functions referenced by the class. If there are any indexes depending
on the operator class, you will need to specify
CASCADE
for the drop to complete.
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.
DROP OPERATOR CLASS will not drop the operator family containing the class, even if there is nothing else left in the family (in particular, in the case where the family was implicitly created by CREATE OPERATOR CLASS). An empty operator family is harmless, but for the sake of tidiness you might wish to remove the family with DROP OPERATOR FAMILY; or perhaps better, use DROP OPERATOR FAMILY in the first place.
