Oh, and to at least give a somewhat more normal postgresql.conf I'd
recommend you at least make the following two changes before doing the
above:
shared_buffers=256MB
checkpoint_segments=32
Those are the two parameters the pgbench test is most sensitive to, so
setting to higher values will give more realistic results.
