In this episode of Database School, I talk with Heikki Linnakangas, co-founder of Neon and longtime PostgreSQL hacker, to talk about 20+ years in the Postgres community, the architecture behind Neon, and the future of multi-threaded Postgres. From paternity leave patches to branching production databases, we cover a lot of ground in this deep-dive conversation.
