The tutorial covers setting up a cron-based GitHub Action that uses pg_dump to export schema and selected table subsets as CSV files, then restores them to a Neon instance. It also addresses multi-table dumps with foreign key integrity, storing connection strings as GitHub Secrets, and briefly touches on PII concerns with partial data dumps. ## Full article daily.dev links to this article rather than hosting it.
