Hi, When overlaying 2 tables that have polygons with st_intersection, i sometimes get linestrings or points back, or a geometrycollection with a combination of types. What i actually want, is that i only get the overlapping parts (that is, overlapping interiors in DE9IM speak) in the geometrytype of the combined geometries. Mostly multipolygon will do fine, so that would make that function a lot simpler.
Now i could make a function that does that, filtering results by their geometrytype. I just wanted to check if something similar already exists? Cheers, WBL -- "Quality comes from focus and clarity of purpose" -- Mark Shuttleworth
