Cypher's pretty much the only thing about Neo4j that I found to be both pleasant-to-use and... well, any good, really. Love seeing it borrowed by other graphDBs. I'm far from being a SQL hater, but being able to bounce into Cypher to replace (at least some large subset of) recursive CTEs would be a huge developer-experience improvement for PostgreSQL, for multi-model DBs.

Example from the n4j Cypher docs, for the curious:

    MATCH (user:User { name: 'Adam' })-[r1:FRIEND]-()-[r2:FRIEND]-(friend_of_a_friend)
    RETURN friend_of_a_friend.name AS fofName

Returns names of friends-of-friends (connected with FRIEND-labeled edges) User nodes having the "name" property "Adam". Stuff like "friend_of_a_friend" is set as an alias for the matched nodes, like in SQL. () denotes a node, [] an edge. (It's been a while, so this explanation may be subtly wrong, but it's close)

I love Cypher too. And PostgreSQL! I wonder how this project compares to Neo4j.

Take a look at OrientDB’s OSQL.

Agreed, Cypher was the thing I loved most about neo4j.

Ever tried 4GL on IBM? Way worse than most.
