[postgis-users] Endpoint and startpoint

This is why I enjoy the challenges of Postgis so much.

There is always something new to learn. (no sarcasm intended) 

I have two lines each of which returns an endpoint.

However the st_endpoint  return on the st_union of those lines returns null.

I would appreciate it if someone could shed some light on why this happens and is there a workaround??
