ALTER TYPE

Name

ALTER TYPE  --  change the definition of a type

Synopsis

ALTER TYPE name OWNER TO new_owner 
ALTER TYPE name SET SCHEMA new_schema

Description

ALTER TYPE changes the definition of an existing type. The only currently available capabilities are changing the owner and schema of a type.

You must own the type to use ALTER TYPE. To change the schema of a type, you must also have CREATE privilege on the new schema. 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 type's schema. (These restrictions enforce that altering the owner doesn't do anything you couldn't do by dropping and recreating the type. However, a superuser can alter ownership of any type anyway.)

Parameters

name

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

new_owner

The user name of the new owner of the type.

new_schema

The new schema for the type.

Examples

To change the owner of the user-defined type email to joe: 

ALTER TYPE email OWNER TO joe;

To change the schema of the user-defined type email to customers: 

ALTER TYPE email SET SCHEMA customers;

Compatibility

There is no ALTER TYPE statement in the SQL standard.
