Maybe I'm missing something, but it seems like all you need to do is
run the data import and the selects in different processes (multiple
backends).
There isn't any way to apply multiple CPUs in a single SELECT, if that's
what you were hoping for. Perhaps you could break down the data
reduction task into independent subqueries, but that will take some
thought :-(
