Tipps:

• The only application that supports working with the database "programmatically" is PDAL.
• For visualization, (check if pointcloud_postgis extension is installed, then:) create views or tables using the casts from pcpoint>geometry and pcpatch>geometry to make tables one can look at in QGIS or GeoServer
