Hey Everyone,

Does anyone know if there is a geometric operator/function that will allow
me to determine if a line segment and a point overlap?  By overlap I mean
that the point lies on the line segment.  I can't seem to do this with the
available geometric operators.

Also, can someone explain to me the difference between how postgres defines
overlap and intersect for its geometric operators/functions.

Please help.

Thanks,
Peter
