Hi again, apparently the extension postgis_sfcgal is not available on Debian, and installing it is not trivial: https://postgis.net/2015/10/25/postgis_sfcgal_extension/ Are there any plans to add a package? Is there anyone who attempted to install and can share his recipe? Thanks. -- Paolo Cavallini - www.faunalia.eu QGIS & PostGIS courses: http://www.faunalia.eu/training.html https://www.google.com/trends/explore?date=all&geo=IT&q=qgis,arcgis
