Most notably, the outcome (not performance) of my query is determined by the presence of an index, which strikes me as odd. I filed my first bug report about 3 months ago and I expect no solution any time soon, but am just not sure I chose the appropriate milestone/component/version: <a href="https://trac.osgeo.org/postgis/ticket/5025" class="">https://trac.osgeo.org/postgis/ticket/5025</a>. Perhaps it’s not even a PostGIS but a PostgreSQL issue. Could you please give me some guidance here?</div><div class="" style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);"><br class=""></div><div class="" style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);">Thanks, Carsten</div></body></html>
