There's some of fatal attraction to the COPY TO command, to it's promise that it can be done in an one-liner. So we rather waste 20 messages and eventually write ten lines of code, while still trying to find the combination of parameters which will give us what we want.

And those ten lines of code are just waiting to happen. Since the first step.
