I know, thanks to you, but why? It supposes to work. seems things within
default's parenthesis are different for no reason.
I mean, insert into mymy values( now() + '60 days'::timespan );
works fine. usually the more strict one (diligitantly casted one)
always works.
I feel pain about it :-) because that was what I tried, and then, since it
did not work, I assumed "default" did not accept expressions.
