Finally, if you are using Java, ObjectWeb has a RAIDb driver that can
transparently distribute databases over a cluster of servers. See

We're getting about 64 million rows inserted in about 1.5 hrs into a
table with a multiple-column primary key - that's the only index.
That's seems pretty good to me - SQL Loader takes about 4 hrs to do the
same job.

PostgreSQL to start a new file on the 1st of each month? Or is this
