The FAQ (copied below) mentioned that native transparent data encryption
might be included in 16. Is it fair to assume that it will support database
level encryption, that is, we can use two encryption keys for two databases
in the same server, respectively? How can one verify that?
The current work to include TDE in PG isn't contemplating a per-database
key option. What's the use-case for that? Why do you feel that you'd
need two independent keys?
I don't feel that key-per-database us useful; I know that key-per-database is useful, since the databases can be different projects for different companies. Each wants it's own encryption key so that no one else can get to their at-rest data.
(pg_dump files will automatically be encrypted, right?)

Ron, this sounds like a revenue opportunity: "Oh you want your own key, well then we'll have to spin up another server just for you so you're all separate and special-like. Way more secure that way."
