So basically it's this: insert into phtomulti_srid values ('1', st_geomfromtext('MULTIPOLYGONZ ( ((0 0 0, 0 1 0, 1 1 0, 1 0 0, 0 0 0)), ((0 0 0, 0 0 1, 0 1 1, 0 1 0, 0 0 0)), ((0 0 0, 1 0 0, 1 0 1, 0 0 1, 0 0 0)), ((0 0 1, 1 0 1, 1 1 1, 0 1 1, 0 0 1)), ((1 0 0, 1 1 0, 1 1 1, 1 0 1, 1 0 0)), ((1 1 0, 0 1 0, 0 1 1, 1 1 1, 1 1 0)))',4326) ); select topology.createtopology('phtomulti_topo',4326,0,'TRUE') as topoid; select topology.addtopogeometrycolumn('phtomulti_topo','public','phtomulti_srid','topo','MULTIPOLYGON Z'); update public.phtomulti_srid set topo = topology.toTopoGeom(geom,'phtomulti_topo',1,0.0000001) where id='1'; Ok, I can reproduce. That geometry is surely very very bad (invalid) but the topology code should't fail. Simplified: select droptopology('t'); select topology.createtopology('t',0,0,true) as topoid; create table t.t (a int); -- just a place holder for the layer select topology.addtopogeometrycolumn('t','t','t','g','MULTIPOLYGON Z'); select topology.toTopoGeom( 'MULTIPOLYGONZ ( ((0 0 0, 0 1 0, 1 1 0, 1 0 0, 0 0 0)), ((0 0 0, 0 0 1, 0 1 1, 0 1 0, 0 0 0)), ((0 0 0, 1 0 0, 1 0 1, 0 0 1, 0 0 0)), ((0 0 1, 1 0 1, 1 1 1, 0 1 1, 0 0 1)), ((1 0 0, 1 1 0, 1 1 1, 1 0 1, 1 0 0)), ((1 1 0, 0 1 0, 0 1 1, 1 1 1, 1 1 0)) )' , 't',1); Can you please file a ticket for this case ?
