Yes, we are discussing either simply using Postgres replication to move data to other regions and use our proxy to rout reads to the datacenter closer to the user (like fly.io). This will have issues with supporting more than ~5 regions.

OR we can separate storage from replication and purpose build a multi-tenant replication service. This will support as many regions as you want (over 200) but it's more work. We will publish an RFC for that.
