DROP STATISTICS

DROP STATISTICS — remove extended statistics

Synopsis

DROP STATISTICS [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]

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. [.term]#CASCADE

[.term]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.
