Removed update trigger on osm_boundary_polygon, which attempted to run `REFRESH MATERIALIZED VIEW` on the table `osm_boundary_polygon_gen_z5`, resulting in the error: "osm_boundary_polygon_gen_z5" is not a materialized view
Fixes#1640
This ensures that place and poi points computed from areas result in a point node that is actually inside the area that it's derived from. Unusual shaped areas (like a banana shape, for example) may produce points that aren't actually contained.
This PR adds indigenous lands to the `boundary` layer by adding new area features for these objects, along with generalization up to z4. It borrows heavily from the technical processing chain of the `park` layer.
I added new `class`, `name`, and `name:xx` attributes to the boundary layer, in order to support the new area features. Should we (or someone extending this schema) come up with new objects to place in the boundary layer in the future, `class` would support additional categories.
