You can't assume anything about result order without including an ORDER BY clause for each column you care about. I was 
simply commenting on the relative expense of a query: an implementation with the right predicate-specific index (and a 
sufficiently smart planner) would -- in principle -- be able to generate ordered results more cheaply than one without 
such an index, simply by walking that index first. You still need to tell it to do so.
