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.
