+ Description

+
+ 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.
+
+
+
+
+
+ SET TABLESPACE
+
+
+ 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
+ .
+
+
+
+
+
+ RENAME
+
+
+ The RENAME forms change 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.
+
+
+
+
+
+ Parameters
+
+
+
+
+ name
+
+
+ The name (possibly schema-qualified) of an existing index to
+ alter.

+
+
+
+
+
+ tablespace_name
+

+
+
+
+
+
+
+
+
+ Notes
+
+
+ This same operations are supported by ALTER TABLE. See also
+ .
+
+
+
+ Changing any part of a system catalog index is not permitted.
+
+
+
+
+ Examples
+
+ To rename an existing index:
+
+ ALTER INDEX distributors RENAME TO suppliers;
+
+
+
+
+ To move a index to a different tablespace:
+
+ ALTER INDEX distributors SET TABLESPACE fasttablespace;
+
+
+
+
+
+
+ Compatibility

+
+ ALTER INDEX is a PostgreSQL extension.
