- Renaming or changing the schema for a shell type should not be allowed.
- I'm allowed to try to add ACL entries or security labels to an
existing shell type. This should be disallowed.
- Changing the schema on a (non-shell) type doesn't work - the type
name is omitted, e.g.
ALTER TYPE pem
SET SCHEMA pemhistory;
Which should be:
ALTER TYPE pem.foo
SET SCHEMA pemhistory;
