Not really, with this solution now you need to manage a non-replicated, non-high-availability mock of Postgres where every user is 'postgres', dealing with the usual remote RPC call issues and latency.
If you need to manage a RDBMS anyways, you probably can manage Postgres; if you can't manage Postgres then it's unlikely that you will be able to manage this solution as well.
