It also adds Ubuntu 26.04 x86_64/arm64 support, refreshes Supabase, pgEdge, PolarDB, Grafana, MinIO, and a batch of infra packages.https://vonng.com/en/ai/dba-agent-body/Sun, 26 Apr 2026 00:00:00 +0000rh@vonng.com (Ruohang Feng)https://vonng.com/en/ai/dba-agent-body/Today’s models are smart enough. What they lack is a body: a deterministic runtime that is observable, controllable, and reversible. Pigsty is evolving from a PostgreSQL distribution into an Agent Runtime, giving DBA and Dev Agents the operational reach and context they need to enter real production environments.https://vonng.com/en/db/agent-state-db/Fri, 20 Mar 2026 00:00:00 +0000rh@vonng.com (Ruohang Feng)https://vonng.com/en/db/agent-state-db/Put an AI agent’s working directory, configuration, and memory on a PGFS mount, and you are effectively storing its state in PostgreSQL. That gives you not only a PITR “time machine,” but also a shared workspace and shared memory for multiple agents across multiple devices.https://vonng.com/en/misc/pigsty-opc/Thu, 19 Mar 2026 00:00:00 +0000rh@vonng.com (Ruohang Feng)https://vonng.com/en/misc/pigsty-opc/Over the last 30 days, pigsty.io served 1.44 million unique visitors, 18.11 million page views, and 1.1 TB of traffic. For a one-person open source project, the real asset here is not ad inventory. It is trust.https://vonng.com/en/pigsty/v4.2/Sat, 28 Feb 2026 00:00:00 +0000rh@vonng.com (Ruohang Feng)https://vonng.com/en/pigsty/v4.2/Pigsty v4.2 turns one stack into 12 enterprise-grade PostgreSQL flavors: multi-master pgEdge, graph-native AgensGraph, MPP Cloudberry, rebuilt compatibility kernels, 461 extensions, infrastructure upgradeshttps://vonng.com/en/pigsty/v4.1/Thu, 12 Feb 2026 00:00:00 +0000rh@vonng.com (Ruohang Feng)https://vonng.com/en/pigsty/v4.1/Same-day production support for PG 18.2 is the core message of Pigsty v4.1. In this cycle, very few vendors shipped day-zero readiness: AWS RDS, EDB, and Pigsty were among them.https://vonng.com/en/ai/agent-moat/Fri, 06 Feb 2026 00:00:00 +0000rh@vonng.com (Ruohang Feng)https://vonng.com/en/ai/agent-moat/A mediocre local who knows the terrain beats a genius parachuted into unknown territory. Intelligence without context is idle. An agent without a runtime is vapor.https://vonng.com/en/pigsty/v4.0/Sat, 31 Jan 2026 00:00:00 +0000rh@vonng.com (Ruohang Feng)https://vonng.com/en/pigsty/v4.0/Pigsty v4.0 is a milestone release — what I’d call “Finished Software.” The real theme: Built for AI Agents and enabling the DBA Agent.https://vonng.com/en/pg/pigsty-relicense/Thu, 29 Jan 2026 00:00:00 +0000rh@vonng.com (Ruohang Feng)https://vonng.com/en/pg/pigsty-relicense/Pigsty switched from AGPLv3 to Apache 2.0. Aren’t you worried about freeloaders? Freeloaders welcome — if you want to become the Debian of databases, a permissive license is table stakes.https://vonng.com/en/pigsty/v3.7/Wed, 03 Dec 2025 00:00:00 +0000rh@vonng.com (Ruohang Feng)https://vonng.com/en/pigsty/v3.7/PostgreSQL 18 becomes the default version, EL10 and Debian 13 support added, extensions reach 437, and Pigsty wins the PostgreSQL Magneto Award.https://vonng.com/en/pg/forge-a-pg-distro/Thu, 27 Nov 2025 00:00:00 +0000rh@vonng.com (Ruohang Feng)https://vonng.com/en/pg/forge-a-pg-distro/PostgreSQL already won. The real battle is the distro layer. Will Chinese developers watch from the sideline or craft a PG “Ubuntu” for the world?https://vonng.com/en/pigsty/v3.6/Fri, 25 Jul 2025 00:00:00 +0000rh@vonng.com (Ruohang
