[postgis-users] Routing in postgis

[Andrea Maschio]

Hello everybody, I just joined this mailing list. I'm going to develop  
a traffic managing application for my graduation thesis, using postgis  
and geoserver. For this i was looking for routing and topology support  
in PostGis, that I started to use since a month.

The question is: at which point is routing support in postgis?  
Supposing that i need to use a graph, and add or delete nodes and / or  
find the shortest path between a and b, there is already a support for  
this kind of operations in Postgis? Or in some external open source  
extension?

Any link to documentation or similare resources is really appreciated.

Thanks

Andrew
