Last week, a blog post by an Uber engineer explained why Uber chose to move from PostgreSQL to MySQL. This article was widely reported and discussed within the PostgreSQL community, with many users and developers expressing the clear sentiment that Uber had indeed touched on some areas where PostgreSQL has room for improvement. I share that sentiment. I believe that PostgreSQL is a very good database, but I also believe there are plenty of things about it that can be improved. When users - especially well-known names like Uber - explain what did and did not work in their environment, that helps the PostgreSQL community, and the companies which employ many of its active developers, figure out what things are most in need of improvement. I'm happy to see the PostgreSQL community, of which I am a member, reacting to this in such a thoughtful and considered way.
