ALTER COLLATION
Name
ALTER COLLATION -- change the definition of a collationSynopsis
ALTER COLLATION name RENAME TO new_name ALTER COLLATION name OWNER TO { new_owner | CURRENT_USER | SESSION_USER } ALTER COLLATION name SET SCHEMA new_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.
