I trying to integrate pgrouting 2.x. I am now using pgrouting 1.x. In version 1 I used
assign_vertex_id. It already dropped in version 2 and became
SELECT pgr_createTopology('roads_r', 0.00001, 'the_geom', 'gid')
It returning query result OK but its not populating source and target field of my road data. Is there any bug in this function?
