Write a mail to your team about the recent incident happened with postgres cluster The postgres cluster appeared in starting state today whereas the replicas were not in sync, potentially this is the cause the leader was not able to switch to available sites. There was no alert received for this but noticed this situation when I had to provide inputs to vendor for previous case which was raised last week Currently you have raised a case with edb to know what can be done to fix along with that raise a channel for application owners to inform them and confirm the impact Looking at the logs it appears that there was excessive checkpoint and potentially caused the standby not in sync, but termination of leader instance is still unknown.

Subject: Update on Postgres Cluster Incident

Team,

I wanted to inform you about a recent incident involving our Postgres cluster. This morning, the cluster was found in a starting state, and it became apparent that the replicas were not in sync. This situation may explain why the leader instance was unable to switch to available sites.

Unfortunately, no alerts were received regarding this issue. I discovered it while preparing inputs for a vendor related to a previous case raised last week.

I have opened a case with EDB to explore potential solutions and have also created a channel for application owners to keep them informed and to assess the impact of this situation.

Initial log analysis suggests that excessive checkpoint activity may have caused the standby to fall out of sync, but the termination of the leader instance remains unclear at this time.

I will keep you updated as more information becomes available. Please let me know if you have any questions or need further clarification.
