+1 for the change from me.

We use PostgreSQL for financial accounting stuff, including plpgsql
triggers and functions etc. And we use numeric for all that. I always
thought that numeric division was exact! :-) I never saw problem,
perhaps because we round to very few digits, but well.

Please apply this patch. I can accept the performance drop, as long as
there won't be bad surprises with correctness.
