<p>I download the china-latest.osm.pbf data file in the geofabrik. I find that the data file has two user id use the same display_name, one is:</p>

<p></p>

<p>another is:</p>

<p></p>

<p>So when i use osmosis to import the file into apidb, some error appears, it says that unable to insert user with id 3642735 into the database, duplicate key value violates unique constraint "users_display_name_idx", Key (display_name)=(Nodes&Roads) already exists. I find the error by transform the file from .pbf to .osc, if i want use the .pbf file, what should i do to deal with the condition?</p>
