[OSM-dev] Reducing osm2pgsql memory usage using a database method

I've just uploaded an experimental version of osm2pgsql which uses
Postgresql database tables for the transient node and segment storage.
This drops the memory usage from >1GB to ~60MB. On the downside, the
import time has gone up from 20 to 100 minutes. I'm sure this can be
improved though with some more database Mojo.

For further details see SVN (utils/osm2pgsql/experimental/readme.txt)
