You know what I love about today's commits? They're the kind of thoughtful, forward-thinking work that makes databases rock solid. We're talking about the unglamorous but absolutely crucial stuff that keeps PostgreSQL running smoothly for millions of applications worldwide.
Let's start with Jacob Champion, who's been doing some really smart preparation work around PostgreSQL's protocol versions. Now, if you're not familiar with database protocols, think of them like the language that your application uses to talk to the database. Jacob made a commit that explicitly reserves protocol…
Now here's what's cool about this - they're not actually using version 3.1 yet, but by reserving it now, they're preventing any confusion down the road.
