Can't do that in plpgsql; it does not like run-time specification of
table or field names.  You could try using EXECUTE but I doubt that
will work either for an assignment to NEW.

I'd suggest using pltcl, which is more amenable to run-time
determination of field names.

You are looking for TG_ARGV[], though this is not your biggest
problem...
