+
+## Work Pools
+
+The `prefect-worker-pg-backup` service automatically creates and listens to the `pg-backup-pool` work pool (type: process).
+
+To deploy a flow to this pool:
+
+```python
+from prefect import flow
+
+@flow
+def my_backup_flow():
+    ...
+
+my_backup_flow.deploy(
+    name="my-backup",
+    work_pool_name="pg-backup-pool"
+)

-## Post-Deployment: Create Work Pool
-
-After the server is running, create a work pool for your workflows:
-
-```bash
-export PREFECT_API_URL=https://prefect.taila5ad8.ts.net/api
-prefect work-pool create backup-pool --type process
