ALTER COLLATION
ALTER COLLATION — change the definition of a collation
Synopsis
ALTER COLLATIONname
RENAME TOnew_name
ALTER COLLATIONname
OWNER TO {new_owner
| CURRENT_USER | SESSION_USER } ALTER COLLATIONname
SET SCHEMAnew_schema
Description
ALTER COLLATION
changes the definition of a collation.
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.)
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.
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.
