1ebd591f19 feat: Enhance documentation and add .gitignore entries
- Add new documentation sections for PostgreSQL installer
  functions and usage examples.  Improves clarity and
  completeness of the documentation.
- Add new files and patterns to .gitignore to prevent
  unnecessary files from being committed to the repository.
  Improves repository cleanliness and reduces clutter.
