How PostgreSQL Works – A Simple Breakdown
Ever wondered how PostgreSQL handles your data behind the scenes? This diagram explains it in a structured way!
✅ Your web application connects to PostgreSQL through multiple connections.
✅ Background processes manage memory, parallel tasks, and optimizations.
✅ Shared memory stores essential buffers for smooth operations.
✅ Auxiliary processes like Auto Vacuum, WAL Writer, and Checkpointer keep the system efficient.
✅ The Postmaster Process ensures everything runs as expected.
✅ Finally, data is stored as Data Files, WAL Files, Archive Files, and Log Files.
Understanding database internals helps developers and DevOps engineers optimize performance and troubleshoot issues effectively.
