using graph model with PostgreSQL

[김세훈]

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.
