Longhorn for Databases

I am planning to run PostgreSQL and MySQL on Kubernetes and want to understand whether Longhorn is suitable for database workloads.

The storage layer must survive pod restarts and node failures, so I need clarification about how Longhorn supports stateful applications.

I also need guidance about performance considerations when using Longhorn volumes for databases that perform frequent writes.

My Kubernetes environment hosts production data, so I want examples showing how Longhorn manages persistent database storage.

I need help understanding backup strategies, replication settings, and storage sizing recommendations for database deployments.

I also want to know whether Longhorn is commonly used for databases in real world Kubernetes environments.
