- Use modern signed-by method for PostgreSQL GPG keys - Auto-detect latest Python 3 version from deadsnakes PPA - Add command tracing (set -x) to show all commands as they run - Display sudo commands upfront before execution - Add user confirmation prompts (y/N) before installation - Improve error handling with set -euo pipefail - Add proper cleanup and verification steps - Use pipx for VisiData installation - Better output formatting with clear section headers Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
