Yeah. The first two formats are ambiguous, in Postgres' mind anyway.
With the US datestyle setting, it will first attempt to parse as mm-dd-yyyy
and if that fails try dd-mm-yyyy. So you'd need to change the datestyle
to Euro to get dd-mm-yyyy input to be parsed reliably.
As of 7.4 this is being tightened up, btw --- it'll be mm-dd-yyyy or error.
But AFAICS this has nothing to do with a default now() insertion,
because that value is never converted to a string before it gets into
the stored column.
