[GENERAL] minimum function

[Gunther Mayer]

Hi there,

I'm busy writing a trigger function in pl/pgsql and find myself in need 
of a minimum() function. I can't see how the builtin min() aggregate 
function can be of any use here since all I want to do is something like

SELECT minimum(5,6) => 5

Any way I can achieve that on one line? I.e. I want it simpler than

IF arg1 < arg2 THEN
   RETURN arg1;
ELSE
   RETURN arg2;
END IF;
