DROP_STATISTICS - remove extended statistics
DROP STATISTICS [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]
DROP STATISTICS removes statistics object(s) from the database. Only the statistics objects 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 dont 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))
