GraphpostgresQL is no longer maintained and hasn't been updated for many years.

I am the person who wrote it. It was a proof-of-concept, written in PL/pgSQL. This made it fairly easy to set up and test but made maintenance and contributions very difficult.

Never ceases to amaze me when someone pops up on HN with a "yeah, I made that, ask me anything".

Nice work, looks like an awesome project.

Very cool! I was not familiar with this project. It does takes a similar approach to query building. It is described in the README as an alpha POC
