Yeah, we'd need to add syntax for that, but it seems useful anyway.
Plan B would be to make the ALTER INDEX RENAME update the associated
constraint too, but that doesn't give you a facility to rename
constraints of other types.
Anyway, point is that I think we should force the index and constraint
names to track each other, rather than complicating matters by
supporting the situation where they are different.
