Ok, granted that, but what's wrong with date_pli (now(), 2)?
It's a similar issue. As a potential counter example, what about
date_pli('foo', 2) or date_pli(inet '1.1.1.1', 2)? There's a cast
from text->date and a cast inet->text. If you allow downcasts and
arbitrary casts you can get some really odd behavior.
Well... this would be a two-step cast.. That was never allowed (was
it?), and I never argued that it should...
