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.
