HI,
I try to remove edges wich have left_face = 0 or right_face=0 and area of the other face is less than one m². My request store this edges in a table : topo.tempface0 And after deleting edges: with p as (select edge_id FROM topo.tempface0) SELECT st_remedgenewface('topo',edge_id FROM p); I've 1978 EDges in the tempface0 Table. After 4 hours only 490 edges are treated, and the time to remove a edge raise after each edge treated. In the topo.edge_data table I've 180 000 Edges, and after 4 hours when I stop the request, I make a vaccum analyse, and the message said : 2 400 000 rows deleted in edge_id_idx !!! I use the same way to remove edges wich have an area<1 and left_face<>0 AND right_face<>0, I'd treated 100 000 Edges in 45 mm ... I use postgis 2.0 .... ? Thanks
