Postgres is going in one direction - for the better. And as a long time Postgres user I&#x27;ve been really happy with it for years. Now with JSONB support I am even happier, as I can build powerful RDBMS + &quot;NoSQL&quot; apps that outperform traditional NoSQL databases.<p>To my disappointment several members of my team have been championing Oracle recently though - presumably because it&#x27;s a safer option and can be managed by others under an SLA.<p>How does one argue against this? With Postgres we&#x27;re not going to get SLA&#x27;s because we know it very well, but with Oracle we would. It&#x27;s mostly perception management IMHO, and I&#x27;m mostly against it. What killer core features does Oracle have that Postgres doesn&#x27;t?
