That won't work in 7.3.

The following works in both 7.2 and 7.3:
area=> select current_date - extract(dow from current_date)::int as start_date,
area-> current_date - extract(dow from current_date)::int + 6 as end_date;start_date |  end_date
------------+------------2002-09-22 | 2002-09-28
(1 row)

Extract returns double precision and so needs a cast to int to work.
