<p><span style="font-size:10.0pt;font-family:"Verdana",sans-serif">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.<o:p></o:p></span></p>
<p><span style="font-size:10.0pt;font-family:"Verdana",sans-serif">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.<o:p></o:p></span></p>
<p><span style="font-size:10.0pt;font-family:"Verdana",sans-serif">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?<o:p></o:p></span></p>
<p><span style="font-size:10.0pt;font-family:"Verdana",sans-serif">Thank you for any hints,<o:p></o:p></span></p>
