Pgsentinel lib added to major upgrade image in gitlab here:
https://gitlab.netcracker.com/PROD.Platform.HA/postgres-operator/-/blob/master/services/upgrade/Dockerfile?ref_type=heads
So thirdparty image doesnt include this, but core-operator include in to patroni by default because this lib need for postgres-exporter
Please fix this issue with helm majorUpgrade, this is required for full scope checks in github pipeline in future
To Reproduce
Run majorUpgrade via helm install or github pipeline
