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.
