Thanks,
seems to be a good idea, but I need some routing on geo position data, but also some graph algorithm depends on machine learning structures,
if I can use the pgRouting project to deal with a „feature graph“ and geo-partial data this will be great, I will test it
Thanks for this hint

Hello,
I’m using in a project Postgresql and PostGIS for a geospatial data model, but now I need also a graph in this structure, so my question is, is there any existing
extension for Postgres to build a graph. I found ltree but this is for tree structures only, not for graphs. In general I have different undirected weighted graphs. So
I need some routing algorithms based on the graph weights, distance calculation between nodes. My first idea was to use a graph database e.g neo4j, but I have
got a limitation, that the whole system should be designed in Postgres.
Did you can give some ideas to build a graph within Postgres
Do you already check the pgrouting [1] project?
