We don't. There is no concept of a lock on a type. For scalar types this is more or less irrelevant anyway, since a scalar has no substructure that can be altered in any interesting way. I'm not sure how hard we ought to work on making composites behave differently. I think it's as likely to cause problems as solve them. regards, tom lane
