The Last DBA#
Hi, I’m Zhilong Liu — a PostgreSQL DBA based in China.
This blog is where I document my deep dives into PostgreSQL internals, production incident analysis, source code walkthroughs, and paper reviews. I write primarily in Chinese on lastdba.com, and I’m building this English section to share key insights with the global PostgreSQL community.
What I Write About#
- Case Studies — Real production incidents and how they were resolved
- Internals — PostgreSQL mechanisms explained from first principles
- Source Code — Deep dives into specific subsystems (vacuum, locking, WAL, planner)
- Paper Reviews — Academic papers on databases, interpreted for practitioners
- AI & Databases — AIOps, MCP, and the intersection of AI with database operations
