IIRC cockroachdb support about every Postgres client.

It “speaks” Postgres.

Not a ton of vendor lock in, since you could always migrate to another Postgres hosting service (although you’d lose some of cockroaches regional features)

Even if CockroachDB uses Postgres wire protocol, it doesn’t mean you can easily migrate all workloads supported by CockroachDB to Postgres. The scaling properties are different.
