Subject: Remove SQL-compatibility function cardinality().  It is not exactly
 clear how this ought to behave for multi-dimensional arrays.  Per discussion,
 not having it at all seems better than having it with what might prove to be
 the wrong behavior.  We can always add it later when we have consensus on the
 correct behavior.
