I have a set of XYZ data which I want to query in PostgreSQL in order to find the volume. I've been trying the ST_Volume on the geometries (have also used ST_MakeSolid and ST_Tesselate) but all queries are giving results of 0. The documentation on ST_Volume for PostGIS is very vague.

I have installed the sfcgal extension as suggested when I looked up the 3D queries
