Database Operations

This skill is internally coherent and appears to be a pure guidance / code-snippet resource for database work. It does not request credentials or install software. Before you act on its suggestions: (1) never run SQL in production without reviewing and testing it in a staging environment; (2) review dynamic SQL (EXECUTE/format) usages to ensure identifiers are validated to avoid injection; (3) be aware that triggers and audit logging can add write overhead and quickly grow storage — plan retention/archival; (4) follow least-privilege practices for any functions/triggers (avoid running as superuser/definer unless necessary); (5) ensure backups and rollback/migration plans are in place before applying schema changes. If you want additional assurance, share specific snippets you plan to run and the target DB environment so they can be reviewed for safety and correctness.
