ALTER
NAME
ALTER INDEX - change the definition of an index
SYNOPSIS
ALTER INDEX name
action [, ... ]
ALTER INDEX name
RENAME TO new_name
where action is one of:
OWNER TO new_owner
SET TABLESPACE indexspace_name
DESCRIPTION
ALTER INDEX changes the definition of an existing index. There are several
subforms:
OWNER
This form changes the owner of the index to the specified user. This
can only be done by a superuser.
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 [create_tablespace(5)].
RENAME
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.
PARAMETERS
name The name (possibly schema-qualified) of an existing index to alter.
new_name
New name for the index.
new_owner
The user name of the new owner of the index.
tablespace_name
The tablespace name to which the index will be moved.
NOTES
These operations are also possible using ALTER TABLE [alter_table(5)].
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.
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.
