This example presents a text-based cheat sheet for PostgreSQL command-line tools, rendering a curated list of psql commands, configuration snippets, and handy SQL queries in a plain markdown document. It shows the core syntax for database management tasks, such as connecting to databases, listing tables and views, managing user roles, and adjusting server logging verbosity, alongside query examples for inspecting indexes, active sessions, and table sizes. The visualization relies on static code blocks and inline formatting, with no interactive graphics or JavaScript libraries; instead, it leverages the raw text content from a gist, emphasizing practical API references like `psql` meta-commands and `pg_stat_activity` queries.
