Building Postgres services on Azure with Charles Feddersen

Why does SQL feel so approachable to some developers, and why do some of them end up spending their careers in the data layer? In Episode 37 of Talking Postgres, Charles Feddersen, who leads product for Postgres at Microsoft, joins Claire to talk about building Postgres services on Azure. We explore his path from classic ASP apps on Microsoft Access to distributed Postgres with Citus, the moment he installed pgAdmin and got pulled deeper into Postgres, and what it takes to build for the many different ways people rely on Postgres today—from Flexible Server and Azure HorizonDB to developer tooling—and why it’s important to support the upstream Postgres open source project.
