PostgreSQL: Performance Revolution - ARM Acceleration and Smart Index Scanning

Today's PostgreSQL development focused heavily on performance optimization with ARM CRC32C acceleration, AVX2-powered page checksums, and smarter index scanning strategies. Notable contributors include John Naylor's ARM crypto extensions work, Peter Geoghegan's index scan improvements, and Etsuro Fujita's foreign data wrapper transaction fixes.

Hey there, PostgreSQL developers! Welcome back to another episode of the PostgreSQL podcast. I'm absolutely buzzing with excitement today because we've got some incredible performance work to dive into from April 5th, 2026. Grab your favorite beverage because we're talking about some seriously cool optimizations…

So here's what's fascinating about today's activity - we didn't have any merged pull requests, but we had seventeen commits that are absolutely packed with performance goodness. Sometimes the most impactful work happens in these focused development sessions, and today is a perfect example.

Let me start with something that's going to make ARM users very happy. John Naylor has been doing incredible work on hardware acceleration, and today he landed ARM CRC32C support using the cryptography extension. If you're running PostgreSQL on ARM processors with the ARMv8 crypto extension, you're looking at…

But John wasn't done there! He also committed AVX2 support for page checksum calculations. This is where things get really exciting for x86 users. We're talking about several-fold performance increases by using 256-bit registers and vector multiplication instead of the older…

Now,…
