[postgis-users] polygon_edges_numbering

[Zmitser Kozhukh]

hello!
I've a question and would be really grateful if someone helps...dunno if it is a trivial thing to do...
I have a polygon boundary and want to number all polygon edges starting from certain vertice for instance in clockwise direction....so the first edge to the left from certain vertice will have number one, then the next one to the left number two etc...until all edges will be numbered.
does anyone have an idea how to do it?
thanks a lot.
