ALTER STATISTICS(7) PostgreSQL 15.7 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.
