If someone is planning to use PostgreSQL as a NoSQL solution, one can use BDR (Bi-Directional Multi-Master Replication -&gt; <a href="https:&#x2F;&#x2F;github.com&#x2F;2ndQuadrant&#x2F;bdr" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;2ndQuadrant&#x2F;bdr</a>) and its global sequences (if needed).<p>There are plenty of other replication solutions available for Postgres, indeed.
