Encryption can be done at 3 different layers (client-application, storage-device, data-base-itself).

Database encryption solution 1:

System disk encryption (cryptsetup/luks)... no modification are needed on the Postgres setup in this case. This also makes clog and textual log encrypted (at rest). If you are using a google cloud VM this guide may be useful.

Database encryption solution 2:

PostgreSQL TDE (transparent data encryption) this postgres feature implement transparent data encryption at rest for the whole database. an example is demonstrated here.

Database encryption solution 3:
