Or we could omit the "CONSTRAINT name" clause from the syntax
altogether.

I think that allowing the names to be different is a bad idea.  That
hasn't been possible in the past and there's no apparent reason why
this feature should suddenly make it possible.  We will have problems
with it, for instance failures on name collisions because generated
names are only checked against one catalog or the other.
