Yes, something like date(now()) might be less subject to breakage as we
monkey around with the semantics of literals and implicit coercions.
BTW, although date(now()) seems okay, I got a rather surprising result
from
template1=# select time(now());
ERROR: Bad time external representation '2001-10-01 18:21:53.49-04'
I haven't dug into this, but surmise that it's trying to do something
involving a conversion to text and back. The less ambiguous form
fails completely:
template1=# select now()::time;
ERROR: Cannot cast type 'timestamp with time zone' to 'time'

Well, I'll take responsibility for fixing that, if you want to spread
the blame ;-). It's my fault that those routines are marked cachable
to begin with --- I hadn't dug into which datetime types had "current"
and which didn't, just marked 'em all noncachable on sight.

We clearly have got to fix the cachability issue, so I have no objection
to you applying your additional changes if you think they're ready.
