ALTER TYPE — change the definition of a type
ALTER TYPEnameOWNER TOnew_ownerALTER TYPEnameSET SCHEMAnew_schema
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.)
nameThe name (possibly schema-qualified) of an existing type to alter.
new_ownerThe user name of the new owner of the type.
new_schemaThe new schema for the type.
