Palak Chaturvedi - Rookie of the Month July 2025

1) Let’s start with you!

Tell us a bit about yourself – your background, current role, and what excites you most in the world of tech.

Hi, I’m Palak, currently working as a Software Engineer at Microsoft on the Azure Database for PostgreSQL team. I graduated with a B.Tech in Mathematics and Computing from DTU. What excites me most about tech is its ability to solve deep, complex problems—from scaling distributed systems to debugging subtle database bugs—and how open source communities like PostgreSQL play a pivotal role in innovation.

2) Why PostgreSQL?

What inspired you to explore or switch to PostgreSQL?

Initially, I got into PostgreSQL during a internship project. But what really pulled me in was its elegant design, powerful features, and the breadth of problems it lets you solve—whether it’s replication, logical decoding, or deep internals like WAL and page formats. Working on real-world data corruption and recovery made me realize how mature and robust the ecosystem is. It’s a database that respects its users and contributors.

3) What are you working on with PostgreSQL right now?

Share the cool stuff you’re building, learning, or solving using PostgreSQL.

At Microsoft, I work on ensuring reliability and performance of Azure PostgreSQL Flexible Server. I’ve worked on pipeline automation for minor version upgrades, debugging logical replication issues, analyzing crash dumps, and investigating cases of storage-level corruption. Recently, I’ve also been contributing to open source tooling around PostgreSQL corruption detection and recovery.

4) What’s been your biggest learning or challenge on this journey?

A lesson, mistake, or an aha moment, we’d love to hear about it!

One of the biggest challenges was understanding how PostgreSQL recovers from data corruption—especially when system catalogs or WAL segments go bad. My “aha” moment was realizing how deep the internals go—like how LSNs are managed or how pg_resetwal can bring a cluster back to life (with caution, of course!). It taught me to respect the balance between abstraction and control in a system like PostgreSQL.

5) Your wisdom to rookies like yourself?

What’s one tip or piece of advice you’d give to someone just starting out with PostgreSQL?

Don’t just treat PostgreSQL like a black box. Spin up a local cluster, break it, and then try fixing it. Whether it’s playing with pg_wal, peeking into pg_class, or setting up logical replication—hands-on learning is the best way to understand how it really works. Also, don’t be afraid to read the source code; it’s extremely well written.

6) Finally, describe your PostgreSQL journey in one word.

Yep, just one!

Empowering.

7) Who or what has influenced your PostgreSQL learning the most?

A mentor, a community, a course, a project, tell us what or who helped you grow.

Definitely the PostgreSQL open-source community. Reading blog posts, mailing list threads, and discussions from contributors like Andres Freund, Thomas Munro, and Melanie Plageman has taught me so much. Also, my mentors and peers at Microsoft have been instrumental in helping me.

8) What’s one PostgreSQL concept or feature you finally understood and felt proud of?

That lightbulb moment when something clicked, we all have one!

Understanding how logical replication works under the hood—from decoding WAL using plugins like wal2json to managing replication slots and ensuring data consistency—was a big win. It’s not just about copying data; it’s about correctness, ordering, and resilience. That moment when I set up a broken replication stream, debugged it, and got it working again was incredibly satisfying.
