Again, I don't want to invent output arguments for functions today ;-).

I agree that a NOTICE would be overkill, and that we need a protocol
change to implement completion conditions (sqlca.sqlwarn) properly.
When that happens, I think the explicit-cast paths in the coercion
routines can easily call the "set a completion condition" routine for
themselves; I see no reason to pass back the condition one level
before doing so.
