Using @PlanetScale's own benchmark data. Removing the volatile and non-optimized polices, pure RLS vs. no RLS (I'm including original data for comparison) This is what performance looks like when security is done right.

The @PlanetScale RLS benchmarks compare per-row function calls vs no RLS. But real RLS policies don’t have to be function-based or evaluated per row. With proper design (stable conditions, InitPlan caching via subqueries, good indexes), you get near-zero overhead + full index utilization.

Interesting take on RLS from @PlanetScale — but the “per-row overhead” they highlight isn’t a limitation of RLS, it’s a consequence of how the policy is written a thread on their take and benchmark 🧵

Postgres RLS sounds great in theory: embedded access control right in the database. In practice, there's complexity in policy configuration, managing your attack surface, and performance implications. Our latest article takes a deep dive into RLS.

This is exactly why, and completely validates everything we do at @constructive_io because RLS is complex and must be managed or you'll make every mistake that @PlanetScale is assuming here. We solve all of these issues, and then some 🚀

happy to share @constructive_io just made the front page of TechDay ⚡️ We open sourced agentic-db → Postgres as the memory layer for AI agents → no more markdown hacks → no more stuffing context into prompts Agents are probabilistic. Your data shouldn’t be!

AI can write the code. Engineers have to make it secure and correct Speaking on a panel representing @constructive_io with AI leaders from @GoogleDeepMind (Sanjeev Dhanda), @abhiaiyer (CTO, @mastra) at the SVB Experience Center on moving from vibe coding → agentic engineering ⚡️ Join us Friday if you're in SF! luma.com/mptofz1l

Yesterday at the @postgresconf I spoke about secure-by-default, modular Postgres ⚡️ As agents start generating applications, the database becomes the trust layer. Security can’t be a follow-up step anymore—it has to be the starting point. This is what we’re building at @constructive_io

Had the pleasure of sitting down Greg Kemnitz and Curt Kolovson about the origin of Postgres, two of the original programmers from when it started 40 years ago! What a journey it's been and such a successful project. More importantly, I’m grateful to call them good friends.

We just open-sourced agentic-db — a Postgres knowledge base and personal CRM you can install in one command. pgpm install agentic-db Vector search, full-text search, fuzzy matching, spatial queries, and auto-embedding triggers. All inside Postgres. npmjs.com/package/agenti…

Hosted @constructive_io Build Night #1 at @AngelList in San Francisco at @founders_cafe Room full of builders actually shipping. Feels like the days when I first came to SF circa 2010. The energy is real! If you're building something cool, you should come to our next one. Appreciate @Kristopherfloyd and @irinson for co-hosting this amazing community event! More to come :)

We're over capacity for @constructive_io's Build Night at @AngelList HQ!! 100+ approved builders working across the agentic stack — agent security, orchestration, infrastructure, trust, voice, fintech agents, and autonomous systems that touch real users and real money.

I tried Modular Postgres (@constructive_io) recently and it changed how I think about database structure Instead of piling everything into migrations: → you define modules → set dependencies → deploy in order Wrote a practical intro on what I learned: @mitchyugan/a-practical-intro-to-modular-postgres-14c828a8b55c" target="_blank" rel="nofollow noopener">medium.com/@mitchyugan/a-…
