Alexander Korotkov cdd6ab9d1f amcheck: Optimize speed of checking for unique constraint violation 
Currently, when amcheck validates a unique constraint, it visits the heap for
each index tuple.  This commit implements skipping keys, which have only one
non-dedeuplicated index tuple (quite common case for unique indexes). That
gives substantial economy on index checking time.
