If I remember the context of the original request, it wasn't about that
anyway, but about dealing with an existing smallint column.

I think you'd have to go and hack the pg_cast entry ... but that cast is
new in 8.1 anyway, so it doesn't apply to Marc's problem (yet).
If we want to make it cover that specific scenario, changing it to AS
ASSIGNMENT would be sufficient; I don't think it needs to be IMPLICIT.
(I generally find cross-type-category implicit casts to be dangerous.)
