NAME
DROP_OPERATOR_CLASS - remove an operator class
SYNOPSIS
DROP OPERATOR CLASS [ IF EXISTS ] \nname\n USING \nindex_method\n [ CASCADE | RESTRICT ]DESCRIPTION
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.
PARAMETERS
IF EXISTS
name
index_method
CASCADE
RESTRICT
NOTES
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.
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.
