 Also, index tuning isn't supported currently on read replicas. Any recommendations seen on a read replica, is one that has been produced on the primary replica after having analyzed the workload recorded in it.

 If you have [high availability](../../reliability/reliability-postgresql-flexible-server.md) or [read replicas](concepts-read-replicas.md) configured on your server, be aware of the implications associated with producing write-intensive workloads on the primary server when recommended indexes are created by the index tuning feature. Be especially careful when creating indexes whose size is estimated to be large.
