How does Postgraphile integrate with Apache AGE?
### Summary

I'm looking to design an open data source to be exposed via GraphQL. In my research, I've found the concept of graph databases quite interesting. I'm also inclined to think that there may be benefits to gain from having the GraphQL API sitting on top of a graph database.

Based on this, I've ended up looking at [Apache AGE](https://age.apache.org/). I'm also planning on going with Postgraphile (even if I can't use AGE in the end). However, I can't seem to find any articles, tutorials or documentation on whether Postgraphile integrates well with AGE. Hence, I have some questions:
1. Is AGE officially supported by Postgraphile?
2. Does Postgraphile integrate well with AGE?
3. Do you agree with my theory that using a graph based backend would have benefits when exposing a GraphQL API?
