Nobody complained when we added sinh, cosh, tanh, asinh, acosh, atanh last year, so I'm feeling skeptical of claims that gcd should be out of scope. Now, those functions were just exposing libc functionality, so there wasn't a lot of code to write. There might be a good argument that gcd isn't useful enough to justify the amount of code we'd have to add (especially if we allow it to scope-creep into needing to deal with "numeric" calculations). But I'm not on board with just dismissing it as uninteresting. regards, tom lane
