Re: Largest & Smallest Functions

But you don't need to create more functions, because you can do this:

select largest(variadic array[1,2,3]);
 largest
---------
       3

As already pointed out, greatest() and least() exist (though they were
added before VARIADIC was, so they don't use it)

Because it saves looking up the type comparison function and doing an
indirect call.
