I have made some good progress on the patch. I realized that pg_upgrade
can't just copy the keys from the old cluster --- they encrypt the user
heap/index files that are copied/linked by pg_upgrade, but also encrypt
the system tables, which initdb creates, so the keys have to be copied
at initdb bootstrap time --- I have added an option to do that. I also
realized that pg_upgrade will be starting/stopping the server, so I need
to add an option to pg_upgrade to allow that prompting. I can now
successfully pg_upgrade a cluster that uses cluster file encryption, and
keep the same keys. All at the same URL.
In addition I have completed the command-line tool to allow changing of
the cluster passphrase, which applies over the first diff; diff at:

My next task is to write a script for Yubikey authentication.
