Re: TDE (Transparent Data Encryption) supported ?

Greetings,

We'd prefer it if you didn't top-post (just write some stuff at the top)
when you respond and post to these mailing lists.

That is a data-at-rest concern and TDE is one approach to addressing it.

Disk-based encryption is available for basically all operating systems
and PostgreSQL works reasonably well on top of encrypted filesystems or
block devices. That's all available today, works quite well to deal
with the "someone stole the disk" or "someone forgot to wipe the drive
before throwing it away" attack vectors.

In particular, I'd encourage you to look at Linux with LUKS for data at
rest encryption. You can then simply run PostgreSQL on top of that and
be protected without any of the complications which TDE introduces.

Thanks,
