blog

Why we included this project

This is a personal technical blog that has run for years, kept by a well-known PostgreSQL expert, and it is one of the largest Chinese-language collections of database internals material on GitHub. The repo holds thousands of articles and notes on PostgreSQL, Greenplum, and related systems, plus a growing set of writing on AI and business topics. Anyone who works with Postgres-family databases will find the practical material here: performance tuning, architecture, and real troubleshooting that is hard to find gathered in one place. The writing comes from hands-on experience rather than documentation summaries, so it reads like a mentor's notebook and is worth browsing by topic. It is not software you deploy, but as a learning resource it gives database practitioners a dense, searchable reference they can clone and keep locally.
