DESCRIPTION

17       ALTER TYPE changes the definition of an existing type.
18
19       You  must  own  the  type to use ALTER TYPE.  To change the schema of a
20       type, you must also have CREATE privilege on the new schema.  To  alter
21       the owner, you must also be a direct or indirect member of the new own‐
22       ing role, and that role  must  have  CREATE  privilege  on  the  type's
23       schema.  (These restrictions enforce that altering the owner doesn't do
24       anything you couldn't do by dropping and recreating the type.  However,
25       a superuser can alter ownership of any type anyway.)
