Dear All,

I have an issue while using Dissolver and Aggregator I get multiarea of 5 polygons, which look merged in the Inspector. But when writing to PostGIS, aggregated geometry is split again into separate polygons. PostGIS is accepting only polygons as geometry. I know that if the PostGIS accepts only single polygon, but writer attempts to load a collection, then a collection will be split. The question is if there's a way to aggregate multiple polygons into one without collection. Single polygon needed only to set the extent of the layer, so envelope like feature will do as well.

Thanks a lot for your answer.
