DROP_OPERATOR_FAMILY - remove an operator family

There is no DROPOPERATORFAMILY statement in the SQL standard.

DROPOPERATORFAMILY drops an existing operator family. To execute this command you must be the owner of the operator family. DROPOPERATORFAMILY 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.

Remove 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.
