The manual did not mention whether its return value is (first arg - second arg) or (second arg - first arg). The order matters because the return value could have a sign. Fix the manual so that it mentions the function returns (first arg - second arg). Patch reviewed by Tom Lane. Back-patch through v13. Older version's doc format is difficult to add more description.
