This is correct, as the controlling name is that of the constraint not
the index. We really should forbid the above entirely, but it's not
a very high-priority issue.
(Somewhat higher priority is to add a RENAME CONSTRAINT capability;
that's on the TODO list. There was a patch for this submitted recently
but it needs work...)
