Rancher Server HA and database (MySQL or Postgres?)

http://docs.rancher.com/rancher/installing-rancher/installing-server/multi-nodes/ mentions that before GA, standing up a HA Rancher Server will be made easier. This Rancher/Server Outage & Reconnection suggests GA is coming at the end of this month and there are still plans to making standing up easier. This https://groups.google.com/forum/#!topic/rancherio/lDr2KCvR88g suggests that MySQL and Postgres are interchangeable. Is this true? If we have to implement HA for the Rancher Server database ourselves, I would prefer to use Postgres because we have something setup for that.


We use H2 for automated testing and don’t use any non-standard or MySQL-specific features. So PostgreSQL theoretically works but we do no testing of it and it will not be “supported” for GA.

So just to confirm, at GA it will be easier to stand up but the burden of maintaining HA for MySQL, Zookeeper and Redis falls on us? I need to know so I can prepare.
