And I'm also interested in developing some unique position/advantage of PostgreSQL in the database world, which means not just being "an alternative to XYZ".
I want to inspire more people to create something new by adopting PostgreSQL and open source. I believe that would be the differentiations.
Totally agreed. As "The Innovator's Dilemma" series say, there are two types of disruptive innovation: new-market disruption and low-end disruption. I believe PostgreSQL is expected on both sides.
