Postgres&#x27; motto is &quot;do it right, or don&#x27;t do it at all&quot;. The developers rather let other projects (or postgres addons) figure out the all the hidden traps and then implement a better-than-average solution on the first try a few years later.<p>Cf. their JSON support, which regularly outperforms dedicated NoSQL databases; they&#x27;re also slowly integrating building blocks for multi-master replication, while still holding out on actually implementing it – seeing MariaDB&#x27;s recent track record with their solution ( <a href="https:&#x2F;&#x2F;aphyr.com&#x2F;posts&#x2F;328-call-me-maybe-percona-xtradb-cluster" rel="nofollow">https:&#x2F;&#x2F;aphyr.com&#x2F;posts&#x2F;328-call-me-maybe-percona-xtradb-clu...</a> ), probably a good decision.
