Error "One or more workers could not be upgraded automatically" During Multi-Node Upgrade

IssueWhen upgrading a multi-node (distributed) Tableau Server installation, you may receive the message
One or more workers could not be upgraded automatically.
- Tableau Server
- Multi-Node (aka distributed or cluster) installation
ResolutionFollow the instructions in the Before you upgrade and Upgrade the primary node and worker nodes sections of Upgrade a Multi-Node (Distributed) Server.
These instructions cover:
- Downloading the worker installer
- Running the worker installer on each worker node directly
- Resuming the cluster upgrade on the primary.
CauseWhen Tableau Server upgrades the version of PostgreSQL used for its internal database such that worker servers require a newer version of the PostgreSQL driver to connect, worker servers need to be upgraded manually.
Additional InformationWhen a Postgres driver upgrade is included in a Tableau Server upgrade, the driver upgrade will cause a prompt at the end of the installation process on each server that a Windows restart is required.
If an automated installation is used with the /SUPPRESSMSGBOXES switch, the restart required dialog will be suppressed, but Windows will still need to be restarted.
