Hello Steven!
The Fly Admin Bot events are from our migration scripts that moved your PG app to Fly Apps V2. We have started with the free postgres apps for now and yours was one of them.
That said, the error started before the migration and was caused by corrupted Stolon ClusterData stored in the Consul. I managed to restore your postgres app by reconstructing the clusterdata and updating its value in Consul.
There was no data loss in the process.
Cheers!
