Work around performance bug
Work around performance bug

This works around a performance bug occuring when the PostGIS extension is loaded after the Pointcloud extension. The work-around involves making sure we firt call a PostGIS function on a connection. We will hopefully find the root-cause of this performance issue and fix it properly.
