ALTER INDEX()			 SQL Commands			 ALTER INDEX()

NAME
       ALTER INDEX - change the definition of an index

SYNOPSIS
       ALTER INDEX name RENAME TO new_name
       ALTER INDEX name SET TABLESPACE tablespace_name

DESCRIPTION
       ALTER  INDEX  changes  the  definition of an existing index.  There are
       several subforms:

       RENAME The RENAME form changes the name of  the	index.	 There	is  no
	      effect on the stored data.

       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  CREATE  TABLESPACE	 [cre‐
	      ate_tablespace(7)].

PARAMETERS
       name   The name (possibly schema-qualified) of  an  existing  index  to
	      alter.

       new_name
	      New name for the index.

       tablespace_name
	      The tablespace to which the index will be moved.

NOTES
       These  operations are also possible using ALTER TABLE [alter_table(7)].
       ALTER INDEX is in fact just an alias for the forms of ALTER TABLE  that
       apply to indexes.

       There  was  formerly  an	 ALTER	INDEX  OWNER  variant, but this is now
       ignored (with a warning). An index cannot have an owner different  from
       its table's owner. Changing the table's owner automatically changes the
       index as well.

       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 an index to a different tablespace:

       ALTER INDEX distributors SET TABLESPACE fasttablespace;

COMPATIBILITY
       ALTER INDEX is a PostgreSQL extension.
