Back in the early days of PostgreSQL, the name was officially changed from Postgres to Postgres95 and finally to PostgreSQL. While the name certainly has it challenges in pronunciation for people new to PostgreSQL, the community has regularly debated a formal name changes. This seems to pop up every now and then, but it always comes back to the same result.
Over the course of a month, there will be 3 PG Days in the US and I'm excited to be going to all of them. Its always a blast to interact with the local communities and see how they are different in different parts of the country.
