How does the Postgres ecosystem compare to Vitess at 1PB+?

Question

I'm not an expert in databases.The MySQL ecosystem has a mature open-source solution for scaling horizontally with Vitess.The Postgres ecosystem seems to have alternatives like Citus, CockroachDB, etc.Are they similarly mature? How do they compare for massive-scale deployments (1PB+ of data, insert-heavy workload)?

There is nothing as mature as Vitess in the Postgres world. But PlanetScale the company behind Vitess is building a Postgres sharding project.
