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. Apache Cloudberry 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.
