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://v45.pgsty.pro/blog/article/pg-pig-clone/ Mon, 06 Jul 2026 00:00:00 +0000 https://v45.pgsty.pro/blog/article/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://v45.pgsty.pro/blog/article/what-is-pg-distro/ Sat, 04 Jul 2026 00:00:00 +0000 https://v45.pgsty.pro/blog/article/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://v45.pgsty.pro/blog/article/dba-agent-body/ Sun, 26 Apr 2026 00:00:00 +0000 https://v45.pgsty.pro/blog/article/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://v45.pgsty.pro/blog/article/agent-state-db/ Fri, 20 Mar 2026 00:00:00 +0000 https://v45.pgsty.pro/blog/article/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://v45.pgsty.pro/blog/article/agent-moat/ Fri, 06 Feb 2026 00:00:00 +0000 https://v45.pgsty.pro/blog/article/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://v45.pgsty.pro/blog/article/forge-a-pg-distro/ Thu, 27 Nov 2025 00:00:00 +0000 https://v45.pgsty.pro/blog/article/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://v45.pgsty.pro/blog/article/dify-setup/ Sat, 22 Jun 2024 00:00:00 +0000 https://v45.pgsty.pro/blog/article/dify-setup/ Dify is an open-source LLM app development platform. This article explains how to self-host Dify using Pigsty. https://v45.pgsty.pro/blog/article/pigsty-intro/ Mon, 24 May 2021 00:00:00 +0000 https://v45.pgsty.pro/blog/article/pigsty-intro/ Yesterday I gave a live presentation in the PostgreSQL Chinese community, introducing the open-source PostgreSQL full-stack solution — Pigsty
