No, it's not.  And my colleague Sorin Iszlai pointed out to me
something else about it: we're getting different numbers reported by
EXPLAIN ANALYSE itself.  How is that even possible?

If we try it here on a moderately-loaded Sun box, it seems we're able
to reproduce it, as well.

How could it be the transport affects the time for the query as
reported by the back end?
