remove extended statistics

DROP STATISTICS \[ IF EXISTS \]

Description
===========

`DROP STATISTICS` removes statistics object(s) from the database. Only
the statistics object\'s owner, the schema owner, or a superuser can
drop a statistics object.

Parameters
==========

`IF EXISTS`

:   Do not throw an error if the statistics object does not exist. A
    notice is issued in this case.

name

:   The name (optionally schema-qualified) of the statistics object to
    drop.

`CASCADE`; `RESTRICT`

:   These key words do not have any effect, since there are no
    dependencies on statistics.

Examples
========

To destroy two statistics objects in different schemas, without failing
if they don\'t exist:

    DROP STATISTICS IF EXISTS
        accounting.users_uid_creation,
        public.grants_user_role;

Compatibility
=============

There is no `DROP STATISTICS` command in the SQL standard.
