ALTER STATISTICS(7)    PostgreSQL 14beta2 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	also be	a direct or indirect
       member of 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.
