This is a PostgreSQL mailing list, and your question has nothing to do with PostgreSQL.

The root cause is that the database size reaches the specified limit and Etcd does not clean it up through rotation. I am aware of this, but despite reviewing the maintenance documentation, I could not find the most appropriate parameter values for this rotation. I am sharing an example of my own Etcd configuration below. I kindly ask you to share your experience on this matter. I am kinda stuck on this issue.
