ALTER TYPE(7)                    SQL Commands                    ALTER TYPE(7)



NAME
       ALTER TYPE - change the definition of a type


SYNOPSIS
       ALTER TYPE name RENAME TO new_name
       ALTER TYPE name OWNER TO new_owner
       ALTER TYPE name SET SCHEMA new_schema



DESCRIPTION
       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.)

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

       new_name
              The new name for the type.

       new_owner
              The user name of the new owner of the type.

       new_schema
              The new schema for the type.


EXAMPLES
       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;



COMPATIBILITY
       There is no ALTER TYPE statement in the SQL standard.
