All Databases Are Just Files

- SQLite and DuckDB are popular because they are simple files that can be easily copied and moved.
- PostgreSQL, while more complex, can also be simplified by understanding its components and file operations.
- Installing PostgreSQL via package managers often leads to treating it as a black box, causing detachment from the system.
- PostgreSQL's default setup includes a system user, data directory, binary, and default database, all named 'postgres', which can be confusing.
- PostgreSQL fundamentally operates by turning SQL queries into filesystem operations, with files stored in a data directory.
- Manually managing PostgreSQL (e.g., using `initdb`, custom config files) can simplify workflows and enhance understanding.
- Understanding PostgreSQL's file structure and processes empowers users to debug, optimize, and manage databases more effectively.
- This approach is ideal for development, prototyping, and testing, though not recommended for production environments.
- Gaining this knowledge helps build cleaner workflows and reduces reliance on treating databases as black boxes.
