If you’re asking this question, you should probably be using RDS or another hosted Postgres service. Personally prefer to operate Postgres on ZFS pools. This offers checksumming (integrity), filesystem-level compression (reduced IO hence faster reads), nvm-e ZIL (faster writes). ZFS also supports snapshotting, so if you run the database in a jail, you can snapshot the entire jail, send it over the network, and start it on another host in exactly the state it was snapshotted.
