I never quite managed to get around to using the osm2pgsql based expiry
code on the main tile server. I still use the ruby scripts written by
Matt

http://trac.openstreetmap.org/browser/applications/utils/export/tile_expiry

I have discussed the expiry scripts with Matt a couple of times and he
found that the osm2pgsql based approach tended to hit the DB quite hard.
He found that even though the osm2pgsql code should in theory produce
more accurate results, the ruby scripts tended to work better overall.
