The koi rules are to stop feeding at 50F.  There is no low temperature limit, other than the pond should not be completely frozen over (to allow oxygen to absorb and other gasses to vent).

Goldfish can survive in ponds in the northern US and Canada as long as the water is deep enough that the pond can't freeze completely. This usually requires that the pond be in-ground and at least a few feet deep.

Your pond doesn't sound as though it will be larger enough for them if the temperature gets below freezing, but they might be okay if the water doesn't. Below 50-55o F, they'll stop feeding, and you should prepare them for the winter by feeding a different food if you plant to keep them outside.

Once in Virginia I saw a koi pond frozen over with koi popsicles inside!

It smelled!

Fishy Jeff: True! The fancy goldfish are also sort of bred to look more beautiful as side-view fish Except for especially bred ranchus and tosakins in Japan (they have warmer climate though...)
