ALTER INDEX name
action [, ... ]
ALTER INDEX name
RENAME TO new_name
where action is one of:
OWNER TO new_owner
SET TABLESPACE indexspace_name
ALTER INDEX changes the definition of an existing index. There are several subforms:
This form changes the owner of the index to the specified user. This can only be done by a superuser.
This form changes the index's tablespace to the specified tablespace and moves the data file(s) associated with the index to the new tablespace. See also CREATE TABLESPACE.
The RENAME form changes the name of the index. There is no effect on the stored data.
All the actions except RENAME can be combined into a list of multiple alterations to apply in parallel.
The name (possibly schema-qualified) of an existing index to alter.
New name for the index.
The user name of the new owner of the index.
The tablespace name to which the index will be moved.
These operations are also possible using ALTER TABLE. ALTER INDEX is in fact just an alias for the forms of ALTER TABLE that apply to indexes.
Changing any part of a system catalog index is not permitted.
