There is also a middle ground, because having the the scheduling process sounds 
like a lot more work than what Josh was proposing.

CREATE TEMP SEQUENCE s;
SELECT relname, s mod <number of backends> AS backend_number
  FROM ( SELECT relname
           FROM pg_class
           ORDER BY relpages
);

Of course, having an actual scheduling process is most likely the most 
efficient.
