The function definition is broken. While it could be fixed (by
explicitly testing fcinfo->nargs, rather than assuming positions
beyond nargs are valid) I am not willing to remove the opr_sanity
check that is complaining. Accordingly, a better solution would be
to make two C-code wrapper functions, one for the single-parameter
and one for the two-parameter case of each function.
