+When `major_version_upgrade_mode` is set to `full` the operator will compare

+can be useful if you have to get rid of outdated major versions in your fleet.
+Please note, that the operator does not patch the version in the manifest.
+Thus, the `full` mode can create drift between desired and actual state.
+
+### Upgrade during maintenance windows
+
+When `maintenanceWindows` are defined in the Postgres manifest the operator
+will trigger a major version upgrade only during these periods. Make sure they
+are at least twice as long as your configured `resync_period` to guarantee
+that operator actions can be triggered.
+
+### Upgrade annotations
+
+When an upgrade is executed, the operator sets an annotation in the PostgreSQL
+resource, either `last-major-upgrade-success` if the upgrade succeeds, or
+`last-major-upgrade-failure` if it fails. The value of the annotation is a
+timestamp indicating when the upgrade occurred.
+
+If a PostgreSQL resource contains a failure annotation, the operator will not
+attempt to retry the upgrade during a sync event. To remove the failure
+annotation, you can revert the PostgreSQL version back to the current version.
+This action will trigger the removal of the failure annotation.

-By default the operator uses a PodDisruptionBudget (PDB) to protect the cluster
-from voluntarily disruptions and hence unwanted DB downtime. The `MinAvailable`
-parameter of the PDB is set to `1` which prevents killing masters in single-node
-clusters and/or the last remaining running instance in a multi-node cluster.
+By default the operator creates two PodDisruptionBudgets (PDB) to protect the cluster
+from voluntarily disruptions and hence unwanted DB downtime: so-called primary PDB and
+and PDB for critical operations.
+
+### Primary PDB
+The `MinAvailable` parameter of this PDB is set to `1` and, if `pdb_master_label_selector`
+is enabled, label selector includes `spilo-role=master` condition, which prevents killing
+masters in single-node clusters and/or the last remaining running instance in a multi-node
+cluster.
+
+## PDB for critical operations
+The `MinAvailable` parameter of this PDB is equal to the `numberOfInstances` set in the
+cluster manifest, while label selector includes `critical-operation=true` condition. This
+allows to protect all pods of a cluster, given they are labeled accordingly.
+For example, Operator labels all Spilo pods with `critical-operation=true` during the major
+version upgrade run. You may want to protect cluster pods during other critical operations
+by assigning the label to pods yourself or using other means of automation.
 
 The PDB is only relaxed in two scenarios:
 
 * If a cluster is scaled down to `0` instances (e.g. for draining nodes)
 * If the PDB is disabled in the configuration (`enable_pod_disruption_budget`)
 
-The PDB is still in place having `MinAvailable` set to `0`. If enabled it will
-be automatically set to `1` on scale up. Disabling PDBs helps avoiding blocking
-Kubernetes upgrades in managed K8s environments at the cost of prolonged DB
-downtime. See PR [#384](https://github.com/zalando/postgres-operator/pull/384)
