[Tile-serving] [osm2pgsql] --apend does not work when data is imported with --flat-nodes (#126)

[Frederik Ramm]

The flatnode file only contains node coordinates, nothing else. The --drop option on import is what kills the (empty) planet_osm_nodes, the planet_osm_ways, and the planet_osm_rels tables. Technically, since --drop destroys updatability, it should also delete the flat nodes file but I believe it doesn't at this time.

Using --append on a database created with --drop is not possible.

The error message should be improved to read "--append only works with databases created with --slim (and without --drop)".
