It must be something weird about 3D detection from QGIS for Postgis layers. I tested with other 3D layers and they work fine, but the layer that fails to work with Z-Values is from a much older Postgis-DB. Maybe it would work fine if we transfer the data to a more modern Postgis-DB ... QGIS display the Metadata as Polygon (PolygonZ) though ... Strange ...

According to my users, this used to work fine in older QGIS versions, but now we can only see the x/y values and not z-values anymore. I just tested it on QGIS 3.22 (LTR) and can conform that the z-values are not displayed in the derived data of the identify tool. Is there any hidden setting that helps us to display the z-values again - or a connection parameter that forces QGIS to treat it correctly as a 3d data set? Thank you for any hints, Andreas
