Seems to work:
regression=# select current_date + s.a as dates from
generate_series(1,3) as s(a);
dates
------------
2004-02-05
2004-02-06
2004-02-07
(3 rows)
Or even:
regression=# select current_date + s.a * '1 week'::interval as dates
from generate_series(1,3) as s(a);
dates
---------------------
2004-02-11 00:00:00
2004-02-18 00:00:00
2004-02-25 00:00:00
