In a changelog entry dated Oct. 6, 2026, the company lists cluster size, replica count, storage and supported Postgres parameters as separately adjustable.\n\nCustomers can create one or more dedicated read replicas in the primary region or place them in another region. There is a boundary on that choice: replicas in another region must use the same cloud provider. The entry does not list eligible regions.\n\nPlanetScale says customers can manage the replicas through its dashboard, API, command-line interface or Terraform.\n\nThe short announcement leaves several deployment questions open, including pricing, plan eligibility and exactly which Postgres parameters can be changed. It points readers to separate dedicated read replica documentation for more detail.","content_kind":"author_paraphrase","explanation":{"feature":"Cluster size, replica count, storage and supported database parameters can differ from the primary cluster, the company says.","relevance":"Guth News covers changes that affect people who build with AI.
