FWIW, increasing sort_mem for the reload process would probably help
with the index and FK rebuilds.  (8.0 rejiggers things so that the
memory constraints for these operations are driven off a separate
variable, but in 7.* you need to muck about with sort_mem.  The
appropriate value for one-off operations is a lot higher than what
you would want multiple competing backends to be using.)
