ALTER STATISTICS(7)      PostgreSQL 16.2 Documentation     ALTER STATISTICS(7)

NAME
       ALTER_STATISTICS - change the definition of an extended statistics
       object

SYNOPSIS
       ALTER STATISTICS name OWNER TO { new_owner | CURRENT_ROLE | CURRENT_USER | SESSION_USER }
       ALTER STATISTICS name RENAME TO new_name
       ALTER STATISTICS name SET SCHEMA new_schema
       ALTER STATISTICS name SET STATISTICS new_target

DESCRIPTION
       ALTER STATISTICS changes the parameters of an existing extended
       statistics object. Any parameters not specifically set in the ALTER
       STATISTICS command retain their prior settings.

       You must own the statistics object to use ALTER STATISTICS. To change a
       statistics object's schema, you must also have CREATE privilege on the
       new schema. To alter the owner, you must be able to SET ROLE to the new
       owning role, and that role must have CREATE privilege on the statistics
       object's schema. (These restrictions enforce that altering the owner
       doesn't do anything you couldn't do by dropping and recreating the
       statistics object. However, a superuser can alter ownership of any
       statistics object anyway.)

PARAMETERS
       name
           The name (optionally schema-qualified) of the statistics object to
           be altered.

       new_owner
           The user name of the new owner of the statistics object.

       new_name
           The new name for the statistics object.

       new_schema
           The new schema for the statistics object.

       new_target
           The statistic-gathering target for this statistics object for
           subsequent ANALYZE operations. The target can be set in the range 0
           to 10000; alternatively, set it to -1 to revert to using the
           maximum of the statistics target of the referenced columns, if set,
           or the system default statistics target
           (default_statistics_target). For more information on the use of
           statistics by the PostgreSQL query planner, refer to Section 14.2.

COMPATIBILITY
       There is no ALTER STATISTICS command in the SQL standard.
