interesting. I just tested (on beta1), that while limit works in this
query:
SELECT generate_series(now(), CAST('infinity'::date AS timestamp), interval '1
hour') limit 3;
i.e. it returns 3 rows instantly,
it doesn't for this query:
SELECT i from generate_series(now(), CAST('infinity'::date AS timestamp),
interval '1 hour') as x (i) limit 3;
which (as far as i understand it) should be the same.
why is it not limiting generate_series in the second example? is it
intentional?
