DROP STATISTICS

Removes 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. WarehousePG issues a notice in this case.

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

CASCADE RESTRICT These key words have no effect, since there are no dependencies on statistics.

Examples

Destroy two statistics objects in different schemas, without failing if they do not exist:

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

Compatibility

There is no DROP STATISTICS command in the SQL standard.
