> @jiayuasu I noticed that after switching from geo.buffer to OverlayNGRobust.union, the complex geometry representation returned from ST_Union_Aggr might change due to the reordering of polygon/polyline vertex. For example: > > New: POLYGON ((1 0, 0 0, 0 1, 1 1, 2 1, 2 0, 1 0)) > > Old: POLYGON ((0 0, 0 1, 1 1, 2 1, 2 0, 1 0, 0 0)) > > They represent the same polygon, but the vertex order has changed. I think this is fine. In addition, we want to make sure the behavior of ST_Union_Aggr is similar to PostGIS ST_Union (array variant): https://postgis.net/docs/ST_Union.html -- This is an automated message from the Apache Git Service.
