Hmm, I don't know enough to give you a confident answer yet. The knowledge sources provided do not specify the exact SQL permissions that Ory Keto requires. However, it's mentioned that Ory Keto requires a production-grade database such as PostgreSQL, MySQL, or CockroachDB for production use. For more detailed information, you may want to refer to the [Ory Keto documentation](
