ALTER TYPE - change the definition of a type
ALTER TYPE name RENAME TO new_name
ALTER TYPE name OWNER TO new_owner
ALTER TYPE name SET SCHEMA new_schema
ALTER TYPE changes the definition of an existing 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.)
name The name (possibly schema-qualified) of an existing type to
The new name for the type.
The user name of the new owner of the type.
The new schema for the type.
To rename a data type:
ALTER TYPE electronic_mail RENAME TO email;
To change the owner of the type email to joe:
ALTER TYPE email OWNER TO joe;
To change the schema of the type email to customers:
ALTER TYPE email SET SCHEMA customers;
