Does anyone run Postgres without PgBouncer? Almost every notable managed Postgres provider bundles a connection pooler like PgBouncer, according to a survey of major providers including AWS RDS, Azure, Google Cloud SQL, Supabase, Neon, DigitalOcean, and others. Only IBM Cloud and Oracle OCI lack a managed pooling option, and both are dismissed as unlikely choices outside enterprise sales cycles. The piece argues connection pooling is effectively a mandatory add-on because Postgres itself handles many connections poorly, and contrasts this with MySQL and MongoDB, which don't require a bolted-on pooler. The wasted effort of every provider building homegrown pooling setups and every user having to learn PgBouncer's quirks (like the lack of LISTEN/NOTIFY support) is framed as evidence that native connection pooling in Postgres itself would be a high-impact improvement.

Stop burning tokens on code review An engineering leader shares why AI-based code review tools like Cursor's BugBot and custom Claude code review skills became too slow, noisy, and expensive (hitting $1000/day in one case) for a team producing thousands of PRs a quarter. The fix that worked: converting team-specific coding rules from markdown guidelines into custom linters, which run in seconds, are deterministic, can run in-editor and on pre-commit hooks, and stop agents from ever pushing bad code. Several example custom lint rules are shared, covering design system consistency, logging, testing conventions, and prose quality.

How MongoDB Reduced PR Review Times with GitDailie A case study describes how MongoDB adopted GitDailies, a GitHub PR alerting and metrics tool, to help engineering teams meet PR review SLAs. Customizable alerts, Slack integration, and personalized dashboards replaced ineffective existing alerting, reportedly cutting review times by up to 54% for one team and over 28% for nearly half the teams involved.
