I really miss hstore slice() (which is a function, not an operator,
but the distinction is is minor IMO) where you can pass array of keys
and get a smaller object back.  This would have to be redefined a bit
since there are new edge cases with jsonb vs hstore but it ought to be
reasonably worked out.
