Review polygon collapse policy in ST_Simplify
|Reported by:||strk||Owned by:||strk|
Current ST_Simplify transforms collapsed polygons into EMPTY polygons, but that's not necessarely a good idea. The goal being generalizing features, _dropping_ the whole location information from them isn't really useful.
This is really depended on use case so we may define policy parameters. A planar subdivision ends up having "holes" if we drop small components. But a central big body with a lot of satellite islands would not get simplified much if we keep all islands.
