People keep trying that :-(. The "typename 'foo'" syntax is for a
*literal constant* only. Instead use multiplication, something like
select (date_trunc('month', now())::date + s.a * '1 month'::interval)::date
from generate_series(0, 11) as s(a)
You'll want the cast back to date as the last step here because
date+interval will give timestamp.
