Can you give us an example you are getting this for? It should be returning a polygon.

I am trying to use pgr_alphashape to convert a set of nodes into a polygon. The documentation description says: Returns the polygon part of an alpha shape. But instead I am getting a geometry_collection instead. I can solve it with st_CollectionExtract, but I m wondering if this is the expected behaviour.
