For instance the number of business days between 2007-04-01 and
2007-04-30:

select sum(case when extract (dow from foo) in(1,2,3,4,5) then 1 else 0 end)
from (select ('2007-04-01'::date + (generate_series(0,'2007-04-30'::date - '2007-04-01'::date)||'days')::interval) as foo) foo;

Unregardedly Easter!
