It is fairly common to modify functions several times before they are
finalised. Using OR REPLACE simply allows you to do it in one step,
instead of DROP FUNCTION... CREATE FUNCTION... every time you change
something.

The OR REPLACE is only an option, you don't have to use it if you don't
want to.
