We had a lot of debugging issues arise out of the backend selection GUC, and I bet approximately nobody uses it. It would have been far more effective to just have the 6 functions in question added a ST_IntersectsCGAL() etc, etc, in terms of the real usage of PostGIS. The backend switch was too smart by 1/2.</div><div><br class=""></div><div>P</div><br class=""><blockquote type="cite" class=""><div class=""><br class=""><br class="">-- <br class=""><div dir="ltr" class=""><div class=""><div dir="ltr" class=""><div class=""><div dir="ltr" class=""><b style="font-size:12.8px" class=""><font color="#666666" class="">Raúl Marín Rodríguez <br class=""></font></b><a href="http://carto.com/" style="font-size:12.8px" target="_blank" class="">carto.com</a><div class=""><br class=""></div></div></div></div></div></div><br class="">
