Sure, people use iSCSI and similar relatively frequently, and as I said
it depends a lot on the controller (client- and server-side), the
workload, and the details of the implementation.
If the iSCSI storage is fast, PostgreSQL will be fast. If the iSCSI
storage has slow writes, PostgreSQL will have slow writes. And so on.
