Hi All,<br>
<br>
Can anyone explain the strange results (see below) I'm getting? <br>
<br>
<tt>~$ apt-show-versions postgresql</tt><tt><br>
</tt><tt>postgresql:all/trusty-updates 9.3+154ubuntu1 uptodate</tt><tt><br>
</tt><tt><br>
</tt><tt>~$ apt-show-versions postgis</tt><tt><br>
</tt><tt>postgis:amd64/trusty 2.1.4+dfsg-3~trusty uptodate</tt><tt><br>
</tt><tt><br>
</tt><tt>~$ apt-show-versions postgresql-9.3-pgrouting</tt><tt><br>
</tt><tt>postgresql-9.3-pgrouting:amd64/trusty
2.2.3-release-ppa1~trusty1 uptodate</tt><br>
<br>
<br>
The first query gives me 4 values and the second has the 'id2' value
empty. <br>
<br>
<tt>SELECT</tt><tt><br>
</tt><tt> pgr_bdDijkstra(</tt><tt><br>
</tt><tt> 'SELECT id_base AS id, source, target, cost_len AS
cost, rcost_len AS reverse_cost FROM _rt_geom_streets_base',</tt><tt><br>
</tt><tt> 11, 6, TRUE, TRUE</tt><tt><br>
</tt><tt> );</tt><tt><br>
