Postgres' motto is "do it right, or don't do it at all". 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. Cf. their JSON support, which regularly outperforms dedicated NoSQL databases; they're also slowly integrating building blocks for multi-master replication, while still holding out on actually implementing it – seeing MariaDB's recent track record with their solution ( https://aphyr.com/posts/328-call-me-maybe-percona-xtradb-cluster https://aphyr.com/posts/328-call-me-maybe-percona-xtradb-clu... ), probably a good decision.
