Shopify’s dashboard shows you orders and revenue, but it won’t let you join that against your ad spend, your support tickets, or a margin calculation you built yourself. It doesn’t support SQL, nor does it keep your data around forever in a form you control. Once your store grows past a certain point, those limits start costing you real time, in spreadsheets stitched together by hand and in reports you can’t quite trust. Your orders, products, customers, and inventory land in a real database you own, ready to join with other systems, query however you like, and keep for as long as you need, not just as long as Shopify decides to show it to you. Shopify has no built-in PostgreSQL export, so every Shopify to PostgreSQL ETL process needs a bridge between Shopify and your database.
