<p>Hi.<br>
I'm trying to apply with osmosis the day diff <a href="http://planet.openstreetmap.org/replication/day/000/001/726.osc.gz">#1726</a> to my osm apidb, but I got this error: <em>duplicate key value violates unique constraint "users_display_name_idx"</em>.<br>
This happens because, apparently, two users (whose ids are <a href="http://www.openstreetmap.org/api/0.6/user/6115593">6115593</a> and <a href="http://www.openstreetmap.org/api/0.6/user/4518891">4518891</a>) have the same display_name ("Андрей Б"), but this should not be possible, according to the current osm apidb <a href="https://github.com/openstreetmap/openstreetmap-website/blob/master/db/structure.sql">schema</a>.<br>
How could this happen on OSM? What should I do in order to address this issue?</p>
