At 100,000 artifacts, deduplication, indexing, snapshots, atomic cutovers, and incremental publishing become the real challenge. SOW puts all of that into one self-contained binary, turning RPM and DEB repository management from ad hoc directory scripts into a recoverable, auditable state system.https://www.yongjiexue.io/en/pg/pg-pig-clone/Mon, 06 Jul 2026 00:00:00 +0000https://www.yongjiexue.io/en/pg/pg-pig-clone/Pig v1.5 adds pig pg clone and pig pg fork, wrapping PostgreSQL 18’s instant cloning capabilities in an agent-native CLI.https://www.yongjiexue.io/en/pg/what-is-pg-distro/Sat, 04 Jul 2026 00:00:00 +0000https://www.yongjiexue.io/en/pg/what-is-pg-distro/Starting with Linux distributions, this essay explains what a “PostgreSQL distribution” actually is: three layers, two paths, and one core idea.https://www.yongjiexue.io/en/ai/dba-agent-body/Sun, 26 Apr 2026 00:00:00 +0000https://www.yongjiexue.io/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://www.yongjiexue.io/en/db/agent-state-db/Fri, 20 Mar 2026 00:00:00 +0000https://www.yongjiexue.io/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://www.yongjiexue.io/en/misc/pigsty-opc/Thu, 19 Mar 2026 00:00:00 +0000https://www.yongjiexue.io/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://www.yongjiexue.io/en/ai/agent-moat/Fri, 06 Feb 2026 00:00:00 +0000https://www.yongjiexue.io/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://www.yongjiexue.io/en/pg/pigsty-relicense/Thu, 29 Jan 2026 00:00:00 +0000https://www.yongjiexue.io/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://www.yongjiexue.io/en/pg/forge-a-pg-distro/Thu, 27 Nov 2025 00:00:00 +0000https://www.yongjiexue.io/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://www.yongjiexue.io/en/pg/dify-setup/Sat, 22 Jun 2024 00:00:00 +0000https://www.yongjiexue.io/en/pg/dify-setup/Dify is an open-source LLM app development platform.
