I applied the attached patch to HEAD. concat(), concat_ws(), left(), right(), and reverse() are in it, but format() and sprintf() are not. It's my understanding that we don't have consensus about the best syntax for the formatting function. We can forget about RAISE. C-like printf syntax is the next candidate, but we should consider about other ones restarting with a clean slate.
Anyway, the newly added functions are useful for developers especially migrated from other database products. Thank you.
