No, which explain why informations are hard to come:-)
This is not a bug, but the absence of a feature.
Note that encryption can occur at many levels, which level is relevant
depends on the threat model:
1. the app can encrypt data in tables
2. the database can encrypt its files
3. the os can encrypt a partition
4. the disks can encrypt their data
1. can be done with a pg extension (ISTM that several exist). 3. depends
on the OS (data at rest encryption), 4 depends on the hardware. Some
people are working on implementing some form of (2).
