I didn't understand that then, and I still don't.  The ALTER TABLE
CLUSTER might need exclusive lock, but it's not going to hold the lock
long enough to be an issue.  I could see that there's a problem with
identify_locking_dependencies believing that two CONSTRAINT items
conflict (do they really?) but not convinced the CLUSTER aspect has
anything to do with it.
