mySQL has more baked in solutions for replication that don&#x27;t require a support contract or a convoluted mess of choosing between half a dozen half baked options for higher availability?<p>Honestly, it&#x27;s the one area that I feel that open-source PostgreSQL is really lacking, and that is a good replication&#x2F;automagic-failover story.  I think MS-SQL is probably the best (but almost as expensive as EnterpriseDB support contract) for the supported versions.  MySQL is probably the best option for a lot of people.<p>That said, I think RethinkDB is a pretty decent all-around option for most workloads at this point.
