Yeah, right, apparently I overestimated chances of inilining, thanks for the hint, Tom. In fact in my project performance problem was caused by the fact that the analogue of f2sql() was declared SECURITY INVOKER and thus could not be inlined :-/. Uhm, does anyone else think inlining tips are worth mentioning in docs or it's just me?
