using graph model with PostgreSQL

[김세훈 <marvtoy92@xxxxxxxxx>]

Hi there,

currently I'm using PostgreSQL with PostGIS extension to handle geospatial data.

In my project I need to apply some graph algorithms like MST for some network of GPS coordinates.

I know there is some way of using Neo4j with PostgreSQL but is there any other way to construct

graph model within PostgreSQL environment?

Any external modules would be welcomed.

Thanks.
