Hi, 2 weeks ago, a user in -tr-genel asked for a function to break path/polygon type data into pieces. He also told that, it creates a bottleneck in the network traffic when they try to receive rows with polygon data of thousands of nodes, while it's enough for them to have polygons partially. AFAIK, there doesn't exist such functions in PostgreSQL. (Please correct me if I'm wrong.) For this purpose, I've coded two simple C procedures: polygon part(polygon, offset, limit) path part(path, offset, limit) I thought it would be nice to see these functions in PostgreSQL and wanted to ask for other users (and developers) ideas. Regards.
