## Logical backups
The operator can manage k8s cron jobs to run logical backups of Postgres clusters. The cron job periodically spawns a batch job that runs a single pod. The backup script within this pod's container can connect to a DB for a logical backup. The operator updates cron jobs during Sync if the job schedule changes. Notes:

The backup script within this pod's container can connect to a DB for a logical backup. The operator updates cron jobs during Sync if the job schedule changes; the job name acts as the job identifier. Notes:
1. The provided `registry.opensource.zalan.do/acid/logical-backup` image implements the backup via `pg_dumpall` and upload of (compressed) results to an S3 bucket; `pg_dumpall` requires a `superuser` access to a DB and runs on the replica when possible.
