--- Migration: Add date_online and shop_score columns to products table
--- These fields are imported from production to improve newsletter recommendation accuracy:
---   date_online  = products.date_ol in production (date product went live on the shop)
---   shop_score   = products.score in production (sales-based popularity score)
---
--- After running this migration, do a full (non-incremental) import to backfill:
---   INCREMENTAL_UPDATE=false node scripts/import-from-prod.js
-
--- Add date_online column (production: products.date_ol)
-ALTER TABLE products ADD COLUMN IF NOT EXISTS date_online TIMESTAMP WITH TIME ZONE;
-
--- Add shop_score column (production: products.score)
--- Using NUMERIC(10,2) to preserve the decimal precision from production
-ALTER TABLE products ADD COLUMN IF NOT EXISTS shop_score NUMERIC(10, 2) DEFAULT 0;
-
--- If shop_score was previously created as INTEGER, convert it
-ALTER TABLE products ALTER COLUMN shop_score TYPE NUMERIC(10, 2);
-
--- Index on date_online for the newsletter "new products" filter
-CREATE INDEX IF NOT EXISTS idx_products_date_online ON products(date_online);
