[postgis-users] source and target vertex for multiple edges

[Travis Kirstine]

Hi all I may have a relatively simple question but I don't have much
experience with routing.  I have a road network with topology built and I'd
like to find the source and target ids from multiple edges.  For example:

For edges e2 and e4  return vertices v2 and v5
For edges e3, e5 and e1 return vertices v1 and v6


v1               v2                v3             v4               v5
         v6
x------------------x-----------------x--------------x----------------x-----------------x
         e1                e2              e3             e4              e5

Thanks
