DROP OPERATOR [FAMILY(7)](https://www.chedong.com/phpMan.php/man/FAMILY/7/markdown)            PostgreSQL 14.23 Documentation            DROP OPERATOR [FAMILY(7)](https://www.chedong.com/phpMan.php/man/FAMILY/7/markdown)



## NAME
       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 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.

## 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 (see Section 5.14).

       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 there are any existing indexes that use operator classes
       within the family. Add CASCADE to drop such indexes along with the operator family.

## COMPATIBILITY
       There is no **DROP** **OPERATOR** **FAMILY** statement in the SQL standard.
