I wonder how it compares to the slightly more well established Postgres-XL.

There is definitely a different approach being taken as Postgres-XL has a supervisor/loadbalancer, and pg_shard seems like every node is capable of doing all actions.

Excited to see it evolve.

Postgres-XL has cluster-wide transaction support, this doesn't.

And cluster wide JOINs as well.
