I posted this to postgis-users but probably it's better here.
Reading the suggested SQL in

more robust results
In Phase 3:
>select ST_Collect(st_simplifyPreserveTopology(geom, 10000)) as geom
could be canged to:
>select ST_SimplifyPreserveTopology(ST_Collect(geom), 10000)) as geom
This guarantees that topology is preserved between edge_data geometries.
This solved various issues I obtained while applying the original SQL to
some intricated geometries.
If you agree on this I can modify the wiki page directly (is it allowed to
All the best,
