This script doesn't do the import, it does the updates. The import is
done from a PBF planet file imported with osm2pgsql. From what I
understand, most of the trick will be in the osm2pgsql options, both for
the import and the updates.

You'd also need to make sure that osmosis, which is used to download
.osc.gz of updates, gives you hstore data.

Especially in the stylesheets.
