Open sourcing our fork of PgBouncer

What this post added

This post contributes to the data infrastructure evolution by detailing improvements made to PgBouncer, a critical component for managing Postgres connection pooling. Specifically, it addresses an authentication bug that impacted HBA authentication and introduces new features for enforcing and dynamically adjusting per-user connection pool limits and per-connection pool limits at runtime. By open-sourcing these enhancements, Cloudflare not only improves its own database infrastructure but also benefits the broader open-source community, aligning with the theme of leveraging and contributing to foundational technologies.
