[Qgis-user] Identify tool and closest vertices (z-values)

Hi,

We have a a Postgis PolygonZ data set an want to query the third 
dimension of the closest vertex. 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
