+1. FWIW, a sample query I wrote for a customer yesterday would have
looked nicer with this function. Here's how the generate_series looked:

generate_series('2016-03-01'::date, '2016-03-31'::date, interval '1
day')::date

But it would have been cleaner to write:

generate_series('2016-03-01'::date, '2016-03-31'::date)

More importantly, though, I don't like that the timestamp version of the
function happily takes date parameters but returns timestamps. I feel
this could lead to some subtle bugs for the unwary.
