Anyone who has ever had root on a database server has that access. There's no technology available that prevents the people responsible for correcting failing RAID volumes from reading blocks from /dev/sda. In theory, yes, there are DRM technologies that prevent you from getting a copy of a song Spotify stores in your cache. But those technologies are not used on multi-gigabyte databases.

The only thing that protects that data is professional ethics, and in extremely paranoid (i.e. airgapped) environments, metal detectors.

Sincerely, God Mode on x DBs, where x > 1.
