Seems like a bug or version mis-match in the client library. That is a new option in v16 so it may not be handled properly. That option is client-only, the client should not be sending it to the server, which the error message indicates it is. Unless you can reproduce with psql you’ll need to check your installation environment (maybe you only have v15 or less client libraries installed?) or file a bug with the driver project.
