I have done a few more things on this patch today, including measurements with a local host and large scaling numbers. One of my hosts was taking for instance around 36.8s with scale=500 using the INSERTs and 36.5s with the COPY when loading data (average of 4 runs) with -I dtg. Greg's upthread point is true as well that for high latency the server-side generation is the most adapted option, but I don't see a reason to not switch to a COPY as this option is hidden behind -I, just for the sake of improving the default option set. So, at the end, applied. -- Michael
