Changes the definition of a collation.

Synopsis

ALTER COLLATION <name> RENAME TO <new_name>

ALTER COLLATION <name> OWNER TO <new_owner>

ALTER COLLATION <name> SET SCHEMA <new_schema>

Parameters

name
The name (optionally schema-qualified) of an existing collation.
new_name
The new name of the collation.
new_owner
The new owner of the collation.
new_schema
The new schema for the collation.

Description

You must own the collation to use ALTER COLLATION. To alter the owner, you must also be a direct or indirect member of the new owning role, and that role must have CREATE privilege on the collation’s schema. (These restrictions enforce that altering the owner doesn’t do anything you couldn’t do by dropping and recreating the collation. However, a superuser can alter ownership of any collation anyway.)

Examples

To rename the collation de_DE to german:

ALTER COLLATION "de_DE" RENAME TO german;

To change the owner of the collation en_US to joe:

ALTER COLLATION "en_US" OWNER TO joe;

Compatibility

There is no ALTER COLLATION statement in the SQL standard.
