# Hack to adjust the generated postgresql CRD YAML file and add missing field
# settings which can not be expressed via kubebuilder markers.
#
# Injections:
#
#  * oneOf: for the standby field to enforce that only one of s3_wal_path, gs_wal_path or standby_host is set.
#    * This can later be done with // +kubebuilder:validation:ExactlyOneOf marker, but this requires latest Kubernetes version. (Currently the operator depends on v1.32.9)
#  * type: string and pattern for the maintenanceWindows items.
