# Postgres Runtime Cutover Status

> **Bottom line:** this branch is **Postgres-capable**, not fully Postgres-backed. Dev deployment now defaults eight existing PG-capable runtime stores to Postgres: auth-owned users/Telegram auth, confirmation-threshold config/history, user addresses, categories, level config, shop settings, reviews, and notifications. Code-level defaults remain Mongo outside that deployment override, and Mongo remains the compatibility store for still-Mongo domains. The category PG path enforces one active visible category per normalized name. As of backend `2.8.36`, the active startup/health/admin/report import surface no longer has non-type top-level `mongoose` or `models/*` imports, and the unmounted legacy marketplace router is no longer re-exported from the marketplace service index; legacy Mongo models are lazy-loaded only when fallback/backfill/maintenance actions run. All PG-backed stores require `PG_URL`.

| Level configuration | PG-backed in dev deployment; code opt-in with `LEVEL_CONFIG_STORE=postgres` | `PointsService` level reads use a level-config facade. `PointTransaction` and user points remain Mongo-backed. |
| Shop settings | PG-backed in dev deployment; code opt-in with `SHOP_SETTINGS_STORE=postgres` | Shop settings controller, seller payment rail resolution, and review enable/disable checks use a shop-settings facade. PG-mode writes mirror back to Mongo. Backend `2.8.32` removed top-level Mongo model imports from this facade; legacy models load only for Mongo fallback/backfill/mirror paths. |
| Marketplace reviews | PG-backed in dev deployment; code opt-in with `REVIEW_STORE=postgres` | Review list/summary/create routes use a review-store facade. PG-mode list responses still hydrate `reviewerId` from the user mirror to preserve frontend shape. Backend `2.8.32` removed top-level Mongo model imports from this facade; legacy models load only for Mongo fallback/backfill/mirror paths. |
| Notifications | PG-backed in dev deployment; code opt-in with `NOTIFICATION_STORE=postgres` or `REPO_NOTIFICATION=pg` | `NotificationService` uses `getNotificationRepo()` for create/list/read/delete/count paths. Backend `2.8.34` adds Mongo→Postgres notification backfill tooling, ordered-runner support, a dry-run path, and `scripts/smoke/notifications-postgres.sh`. Deployment `8764fdf` defaults `NOTIFICATION_STORE=postgres` in dev and Gatus requires the notification store mode. |

Deployment `8764fdf` defaults `NOTIFICATION_STORE=postgres` in dev and Gatus requires the notification store mode. Backend `2.8.37` fixes repository mode aliasing so this `postgres` store flag resolves to the Drizzle notification repo rather than Mongo. |
| Repository implementations | Present with first payment-ledger runtime seam | `src/db/repositories/*` and Drizzle schemas exist for the target architecture. Backend `2.8.20` wires `fundsLedgerService` appends/balance reads through `getPaymentRepo()`, making that ledger slice controllable by `REPO_PAYMENT=mongo|dual|pg`. The broader payment, marketplace, and points services still need method-by-method service wiring before their repo flags are safe runtime cutovers. |
| Oracle quote persistence | Conditional runtime PG write | `/api/payment/request-network/intents` lazily imports `quoteRepo` only when `ORACLE_QUOTING_ENABLED=true`; it writes `payment_quotes` if the PG parent payment row exists, mirrors to Mongo `Payment.quote`, and records `pg_dualwrite_gaps` if PG is behind. |
| Backfill/verify scripts | Available as operator tooling | `MIGRATION_PG_URL` drives backfill scripts; guards restrict allowed target hosts. The marketplace-core runner group now backfills users/categories, request templates, purchase requests, seller offers, and the post-offer `selectedOfferId` remap in dependency order. These scripts are not run automatically by app startup. |

| Points/referrals/transactions | Repository-backed, default Mongo | `PointsService` uses `getPointsRepo()` and level configuration is PG-capable, but `REPO_POINTS` defaults to Mongo and point transaction/user-point flows have not been flipped in dev. |
| Chat/messages | Repository-backed, default Mongo | Chat service uses `getChatRepo()`, but `REPO_CHAT` / `CHAT_STORE` defaults to Mongo and chat is still treated as a document-shaped domain until a deliberate PG cutover. |

| Disputes/blog/content/admin cleanup | Mixed | Disputes and blog are repository-backed, but their code defaults still resolve to Mongo until `REPO_DISPUTE`/`BLOG_STORE` are flipped. Admin cleanup still lazy-loads and calls Mongoose models directly for maintenance cleanup/stat/user-data actions. |
| Runtime config outside confirmation thresholds | MongoDB | `ConfigSetting` and `ConfigSettingHistory` are PG-capable for confirmation thresholds only; any future admin-editable settings need to route through the same config-store boundary before they count as cut over. |
| Telegram link/session/temp verification | PG-backed in dev deployment; code default MongoDB | These records move with `AUTH_STORE=postgres`. Dev compose defaults that flag to `postgres`; environments without the override remain Mongo until the flag is flipped. |

| `PG_URL` | Makes PG code importable/reachable. Required for any `*_STORE=postgres` flag; does not cut over unrelated app domains by itself. |
| `MIGRATION_PG_URL` | Used by backfill scripts and migration runbooks; not part of normal request handling. Marketplace-core dry-run/non-dry backfills also require `MIGRATION_MONGO_URL`. |
| `REPO_PAYMENT` | Code default `mongo`. As of backend `2.8.20`, funds ledger appends and balance reads use this flag through `getPaymentRepo()`. Do not flip broad payment runtime to `pg` yet; most payment services still call Mongoose directly. |
| `REPO_USER`, `REPO_POINTS`, `REPO_MARKETPLACE`, `REPO_DEFAULT` | Repository factory flags exist, but broad services are not yet wired through the factory. Treat them as migration controls that need integration verification before relying on them. The factory lazy-loads PG/dual implementations so importing it in Mongo mode does not require `PG_URL`. |

| `ORACLE_QUOTING_ENABLED` | Enables server-side quote computation and the only current PG write path in normal checkout: `payment_quotes`, when a PG parent row can be resolved. |
