NAMEDROP_OPERATOR_FAMILY - remove an operator family SYNOPSISDROP OPERATOR FAMILY [ IF EXISTS ] name USING index_method [ CASCADE | RESTRICT ] DESCRIPTIONDROP 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 of the operators or functions referenced by the family. If there are any indexes depending on operator classes within the family, you will need to specify CASCADE for the drop to complete. PARAMETERSIF 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 (see
Section 5.15).
RESTRICT Refuse to drop the operator family if any objects depend
on it. This is the default.
EXAMPLESRemove the B-tree operator family float_ops: DROP OPERATOR FAMILY float_ops USING btree; This command will not succeed if there are any existing indexes that use operator classes within the family. Add CASCADE to drop such indexes along with the operator family. COMPATIBILITYThere is no DROP OPERATOR FAMILY statement in the SQL standard.
