4 ALTER STATISTICS — change the definition of an extended statistics
9 ALTER STATISTICS name OWNER TO { new_owner | CURRENT_ROLE | CURRENT_USER | SESSI
11 ALTER STATISTICS name RENAME TO new_name
12 ALTER STATISTICS name SET SCHEMA new_schema
13 ALTER STATISTICS name SET STATISTICS { new_target | DEFAULT }
17 ALTER STATISTICS changes the parameters of an existing extended
18 statistics object. Any parameters not specifically set in the ALTER
19 STATISTICS command retain their prior settings.
21 You must own the statistics object to use ALTER STATISTICS. To change a
22 statistics object's schema, you must also have CREATE privilege on the
23 new schema. To alter the owner, you must be able to SET ROLE to the new
24 owning role, and that role must have CREATE privilege on the statistics
25 object's schema. (These restrictions enforce that altering the owner
26 doesn't do anything you couldn't do by dropping and recreating the
27 statistics object. However, a superuser can alter ownership of any
28 statistics object anyway.)
33 The name (optionally schema-qualified) of the statistics object
37 The user name of the new owner of the statistics object.
40 The new name for the statistics object.
43 The new schema for the statistics object.
46 The statistic-gathering target for this statistics object for
47 subsequent ANALYZE operations. The target can be set in the
48 range 0 to 10000. Set it to DEFAULT to revert to using the
49 system default statistics target (default_statistics_target).
50 (Setting to a value of -1 is an obsolete way spelling to get the
51 same outcome.) For more information on the use of statistics by
52 the PostgreSQL query planner, refer to Section 14.2.
56 There is no ALTER STATISTICS command in the SQL standard.
