To help move this forward, I created a new wiki TDE section titled "TODO
for Full-Cluster Encryption" and marked some unresolved items with
question marks:
https://wiki.postgresql.org/wiki/Transparent_Data_Encryption#TODO_for_Full-Cluster_Encryption
I have also updated some of the other text to match conclusions we have
made.
I know some of the items are done, but if we have agreement on moving
forward, I can help with some of the missing code. This looks doable
for PG 13 if we start soon.
