Increasing sort_mem dramatically (say, 128M) will greatly speed things
up - especially with foriegn key creation and index creation (Those two
things are what takes the longest in a PG restore). Be sure to turn it
back down to something normal after the store (If you didn't change it
on a single session)

However a 500k row table is not terribly big.. How big is the dump in
terms of MB?
