Blocking cutovers to save replication slots
PlanetScale’s Postgres operator blocks cutovers that would leave logical replication slots out‑of‑sync. By requiring `failover=true` on slots and turning on `hot_standby_feedback` and `sync_replication_slots`, the operator ensures slots survive a primary promotion, preventing downstream CDC consumers from losing data.
