We have a perl program that loads data into Postgres version 7.3.1
using deletes and inserts.

We find that the load times are about 50% slower when we use a
RAID5 disk system as compared to when we use RAID0

Are there any postgres configuration parameters that we can set to improve
the performance on RAID5?
