All that has happened is that the *implicit* casting is gone. They will
now simply produce errors, the fix being to explicity cast it to the
type you wanted, rather than the system guessing.
The example you gave is not a problem, because unknown != text. It's
only an issue if you're doing things like performing text operations
(substr,like etc) on non-text things (like dates, numbers, etc).

No.

Seems to me the easiest way would be to try it out on an 8.3
installation and exercise each query once. There may be a better way
but I don't know it...
Have a nice day,
