The current plan is to enhance the Mapnik update process so that the
weekly import will go into a temporary DB. The export to can carry on
rendering the existing data during the import. Then old data will be
dropped and the new data put in its place which should only take a few
seconds.
The above plan is fine in principle but I need to work out an automated
script which does all the steps in the right sequence an make sure that
the partition containing the database does not run out of disk space.
