Folks, A client is asking us about data security, and keeping data encrypted on disk. I recall there was some discussion about this before, including things like for it to be secure an operator would need to put in a key when the disk is mounted, that once it is mounted anyone with permissions to the disk can read it, etc. Given these drawbacks, I'm wondering if anyone has used an encrypted fs for PostgreSQL and if so, what they found in terms of speed. Would this be a big hit, or would it be pretty low impact? Also, does it cause any potential problems with recovery from a crash, etc?
