Postgres is the last SQL DB thing mentioned?<p>No mention of RethinkDB (<a href="https:&#x2F;&#x2F;rethinkdb.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;rethinkdb.com&#x2F;</a>) ?<p>SQL is good if your data is &quot;unchanging&quot;? Schema migrations happen, SQL can be sharded and scaled to multiple servers, and the fact is, unless you&#x27;re facebook or google, you probably won&#x27;t even need it. Didn&#x27;t reddit run postgres since it began?<p>Glad I skimmed this.
