Unless I'm wrong, pgsodium will not protect you from Admin team. The "postgres"
role will always be able to read your keys or meta-data to derive them from the
master key if they are stored inside the database… and root might be able to
scan the memory to find the master key I suppose.

Storing the keys outisde the database means code level change.

Your best bet would be the Transparent Column Encryption patch, but it is
stalled for one year.

In last resort, I suppose selinux/sepgsql machinery can lock everything the way
you want, even without encryption…

good luck.
