DROP OPERATOR FAMILY

DROP OPERATOR FAMILY — remove an operator family

Synopsis

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

Description

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

DROP OPERATOR FAMILY includes dropping any operator classes contained in the family, but it does not drop any operators or functions referenced by the family. If any indexes depend on operator classes within the family, you will need to specify CASCADE to complete the removal.

Parameters

IF EXISTS

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

name

The name (optionally schema-qualified) of an existing operator family.

index_method

The name of the index access method the operator family is for.

CASCADE

Automatically drop objects that depend on the operator family, and in turn all objects that depend on those objects.

RESTRICT

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

Examples

# Remove the B-tree operator family float_ops:

DROP OPERATOR FAMILY float_ops USING btree;

# This command will not succeed if any existing indexes use operator classes within the family. Add CASCADE to drop such indexes along with the operator family.
