If I understand correctly, Postgis does not handle NULL altitude in 3D
geometries.
Hence, when using ST_Force3D, it sets the altitude to 0, which I find a
bit inconvenient (and dangerous).
1. Is there any ongoing or potential development towards handling null
altitude in geometries or this is not technically possible?
2. Do you have any good workaround? Like using -9999 and creating your
own ST_Force3D?
Thanks a lot,
Denis</pre>
