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.
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.
