For AI agents: The documentation index is at https://docs.digitalocean.com/llms.txt. Markdown versions of pages use the same URL with index.html.md in place of the HTML page (for example, append index.html.md to the directory path instead of opening the HTML document).

PostgreSQL Advanced Edition clusters now support 20 additional extensions beyond the pre-installed pg_repack, pg_stat_statements, pgaudit, plpgsql, and vector extensions, including pg_trgm, pgcrypto, citext, and uuid-ossp. You can enable them with CREATE EXTENSION. See Supported PostgreSQL Extensions.
