Andres wrote two blog posts on Postgres' connection scalability behavior. Part 1 analyzed current bottlenecks in Postgres 13 (this blog post) and Part 2 described the work done in Postgres 14 to make improvements on the biggest bottleneck (linked from Jeff's comment above).
Part 2 hit Hacker News first, so the appearance on HN was a bit out of order.
