Your BigAnimal Cluster was created by a free trial user.
PG cluster status becomes "Cluster is in an unrecoverable state, needs manual intervention" but not 'Cluster is in healthy state'.
You also can not access DB with the connection string you used before.
Disk is full, no space left to write xlog.
You can provision a single cluster with up to 4GB disk storage in either PostgreSQL or EDB Postgres Advanced Server.
1. Workaround: Delete the current cluster and restore from the deleted cluster before the cluster is expired. Then you will have a new cluster with the old data. Impact: PG Cluster ID will be changed.
2. Contact BigAnimal Support to get further technical support if you have any concerns.
3. Contact EDB Sales via BigAnimal portal or via https://www.enterprisedb.com/contact to get more product details. With the paid account, you can create a cluster with large volume.
