Or another crazy idea is to append "random length" dummy data into compressed FPW. Which would make it really hard for an attacker to guess the information from WAL location.
It makes the signal more noisy, but you can still mount the same attack if you just average it over more iterations. You could perhaps fuzz it enough to make the attack impractical, but it doesn't exactly give me a warm fuzzy feeling.
