The work-around I applied when I stumbled across this was just to apply 
an explicit cast before my function's RETURN. That neatly solves my 
particular problem (which I at first thought was a formatting issue 
somewhere in my app).

The real danger with this is the opportunity to end up with occasional 
bad data in tables, quite possibly unnoticed. If I'd come across this in 
an existing system rather than a new app I'm pretty sure it would have 
confused me for a lot longer than it did.
