DROP OPERATOR FAMILY

remove an operator family

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
    [???](#ddl-depend)).

`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.
