Yes, because the default values will normally be converted to the column
data type at the time the CREATE TABLE is done. What you want is to
leave them as text until an INSERT happens. The trick looks like this:
dt datetime default text 'now'
or
dt datetime default 'now'::text

That should work too, although it's pretty ugly for all except the
datetime case. (Do you really need to write the conversion functions
explicitly? At least in recent Postgres releases, I think they should
get added for you...)
