[Tile-serving] [openstreetmap/osm2pgsql] Something wrong with indexes during import (#1436)

[Jochen Topf]

In your `osm2pgsql.process_way` function you basically write all ways into the `lines` table in stage 1 **and** stage 2. In stage 2 you will see all ways that are part of a boundary relation again. Those are a lot of ways and they will all get deleted from the `lines` table and then re-inserted. This is, of course, unnecessary, because the resulting entry in the table will be the same, but osm2pgsql doesn't know that. You can check `osm2pgsql.stage == 1` to avoid that.
