DROP STATISTICS

remove extended statistics

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.

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.
