PostgreSQL and Academia: Establishing Partnership

PostgreSQL, maintained as an open source project, is an ideal database for teaching relational theory and demonstrating database internals. However, so far, few academic institutions have adopted PostgreSQL for their educational needs.

One of the goals of Prairie Postgres NFP, a Midwest non-profit, is to bridge the gap between Industry and Academia with the help of PostgreSQL. We advocate for using PostgreSQL in data management courses and invite students and faculty to participate in PostgreSQL conferences and meetups.

In this talk, we will share our successes in this journey and highlight the problems we are still trying to solve.
