DROP_STATISTICS

remove extended statistics

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

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.

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.

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;

There is no DROP STATISTICS command in the SQL standard.

ALTER STATISTICS (ALTER_STATISTICS(7)), CREATE STATISTICS (CREATE_STATISTICS(7))
