In addition to the other suggestions that have been posted (using a
procedural language more suitable to mathematical ops, etc) I noticed that
you are using a RAISE in the PostgreSQL version that you are not in Oracle.
I am curious as to what the difference is if you use the RAISE in both or
neither cases.
