Well, I'd rather it didn't change at all. IMHO it's a feature, not a bug. In
any case, if it does get changed we'll have to go through the documentation
and work out whether we mean current_timestamp or now(). I think most people
actually want now().

Fortunatly where I work we only use now() so it won't really matter too
much. Is there a compelling reason to change?
