You could probably improve the index-create time by temporarily
increasing sort_mem.  It wouldn't be unreasonable to give CREATE INDEX
several hundred meg to work in.  (You don't want sort_mem that big
normally, because there may be many sorts happening in parallel,
but in a data-loading context there'll just be one active sort.)
