I am using osm2pgrouting to import an osm file to a database.<br>In the first time it worked fine but when I try to append some data to the database I get the following error:<br><br>create Ways failed: ERROR: more than one row returned by a subquery used as an expression<br>
<br>How could I fix it?<br><br>I am following this (<a href="http://www.pgrouting.org/docs/tools/osm2pgrouting.html">http://www.pgrouting.org/docs/tools/osm2pgrouting.html</a>) tutorial. <br><br>
