You can't just compare graphs like that without factoring in the cloud. PostgreSQL is a first-class, cloud managed, supported database in the top three cloud providers whereas Oracle is not. It's a massive impediment to adoption and is in no way a reflection of the database itself.
Either way nothing to suggest that PostgreSQL is any way dominating.
and lots more of these pretty small players - that still drive adoption.
Then it's very well support on AWS / GCP / Azure
So postgresql is just crushing it in terms of adoption.
I honestly have not seen major Oracle offering in a bit.
Looking at what tech companies are building on is oracle a major player these days. They used to be THE pretty much only player - those days feel gone by now.
Your own comment suggests that Postgres is dominating over Oracle, simply by saying that it’s been adopted as a major offering by the top 3 cloud providers. How is that not a reflection of the database?
