This document provides an overview and introduction to PostgreSQL for new users. It covers getting started with PostgreSQL, including installing it, configuring authentication and logging, upgrading to new versions, routine maintenance tasks, hardware recommendations, availability and scalability options, and query tuning and optimization. The document is presented as a slide deck with different sections labeled by letters (e.g. K-0, S-0, U-0).
