I've now spent 6 hours trying to find a way to do something similar, as you can do in Neo4j, where you find relations up to depth 5, in PostgreSQL.
The issue is, I have to tables. One with persons, another one with relations (incoming ID and outgoing ID) to have a many to many relationship.

I'm at the point where I just don't care getting it to work. In Neo4j it's a fucking one liner, so why the fuck am I getting assigned to do this in PostgreSQL?
To prove a point? Well fuck you, I'm done with this shit.
