This is my first shot at using postgresql's geometric functions I have a passel of lines defined by x1 y1 x2 y2 I created a table with type lseg and loaded it I start by finding the line that has an end closest to 0,0 Now I want to find the next line that has an end closest to the first line's other end and so on I want to find the shortest path I see there are a lot of geometric operators but I am a bit baffled Can someone offer suggestions or reading references
