+* ``PGVECTOR_CONNECTION_STRING`` feeds ``psycopg.connect()`` directly

+silently upgrades the legacy ``postgresql+psycopg2://`` prefix since
+psycopg2 is no longer in the project.
+
+This module is deliberately separate from ``application/core/settings.py``

+description: Set up PostgreSQL as the user-data store for DocsGPT and migrate from MongoDB at your own pace.
+---
+
+import { Callout } from 'nextra/components'
+
+# PostgreSQL for User Data
+
+DocsGPT is progressively moving user data (conversations, agents, prompts,
+preferences, etc.) from MongoDB to PostgreSQL, one collection at a time.
+Each collection is guarded by a feature flag so you can opt in and roll
+back instantly. MongoDB stays the source of truth until you cut over
+reads; vector stores (`VECTOR_STORE=pgvector`, `faiss`, `qdrant`, `mongodb`, …)
+are unaffected.
+
+<Callout type="info" emoji="ℹ️">
+  Which collections are available today is in the [Status](#status)
+  table below. That table is the only part of this page that changes
+  release to release.
+</Callout>
+
+## Setup
+
+1. **Run Postgres 13+.** Native install, Docker, or managed (Neon, RDS,
+   Supabase, Cloud SQL…) — all work. You'll need the `pgcrypto` and
+   `citext` extensions, both standard contrib modules available
+   everywhere.
+
+2. **Create a database and role** (skip if your managed provider gave
+   you these):
+
+   ```sql
+   CREATE ROLE docsgpt LOGIN PASSWORD 'docsgpt';
+   CREATE DATABASE docsgpt OWNER docsgpt;
+   ```
+
+3. **Set `POSTGRES_URI` in `.env`.** Any standard Postgres URI works —
+   DocsGPT normalizes it internally.
+
+   ```bash
+   POSTGRES_URI=postgresql://docsgpt:docsgpt@localhost:5432/docsgpt
+   # Append ?sslmode=require for managed providers that enforce SSL.
+   ```
+
+4. **Apply the schema** (idempotent — safe to re-run):
+
+   ```bash
+   python scripts/db/init_postgres.py
+   ```
+
+## Migrating data
+
+Two global flags, no per-collection knobs — every collection marked ✅
+in the [Status](#status) table is handled automatically.
+
+1. **Enable dual-write.** Writes go to both Mongo and Postgres; Mongo
+   remains source of truth. Set the flag in `.env` and restart:
+
+   ```bash
+   USE_POSTGRES=true
+   ```
+
+2. **Backfill existing data.** Idempotent — re-run any time to re-sync
+   drifted rows. Without arguments, backfills every registered table;
+   pass `--tables` to limit.
+
+   ```bash
+   python scripts/db/backfill.py --dry-run           # preview everything
+   python scripts/db/backfill.py                      # real run, everything
+   python scripts/db/backfill.py --tables users      # only specific tables
+   ```
+
+3. **Cut over reads** once you trust the Postgres state:
+
+   ```bash
+   READ_POSTGRES=true
+   ```
+
+   Rollback is instant: unset `READ_POSTGRES` and restart. Dual-write
+   keeps Postgres up to date so you can flip back and forth.
+
+<Callout type="warning" emoji="⚠️">
+  Don't decommission MongoDB until every collection you use is fully
+  cut over. During the migration window, Mongo is still required.
+</Callout>
+
+## Status
+
+_Last updated: 2026-04-10_
+
+| Collection | Status |
+|---|---|
+| `users` | ✅ Phase 1 |
+| `prompts`, `user_tools`, `feedback`, `stack_logs`, `user_logs`, `token_usage` | ⏳ Phase 1 |
+| `agents`, `sources`, `attachments`, `memories`, `todos`, `notes`, `connector_sessions`, `agent_folders` | ⏳ Phase 2 |
+| `conversations`, `pending_tool_state`, `workflows` | ⏳ Phase 3 |
+
+Schemas for **every** row above already exist after `init_postgres.py`
+runs. What's landing progressively is the application-level dual-write
+wiring and the backfill logic for each collection. Once a collection
+is ✅, enabling `USE_POSTGRES=true` and running `python scripts/db/backfill.py`
+picks it up automatically — no per-collection config change.
+
+## Troubleshooting
+
+- **`relation "..." does not exist`** — run `python scripts/db/init_postgres.py`.
+- **`FATAL: role "docsgpt" does not exist`** — run the `CREATE ROLE` /
+  `CREATE DATABASE` statements from step 2 as a Postgres superuser.
+- **SSL errors on a managed provider** — append `?sslmode=require` to
+  `POSTGRES_URI`.
+- **Dual-write warnings in the logs** — expected to be non-fatal. Mongo
+  is source of truth, so the user-facing request succeeds. Re-run the
+  backfill to re-sync whichever rows drifted.

+# Confluence Connector
+
+Connect your Confluence Cloud workspace to upload and process pages directly as an external knowledge base. Supports page content and attachments (PDFs, Office files, text files, images, and more). Authentication is handled via Atlassian OAuth 2.0 with automatic token refresh.
+
+## Setup
+
+<Steps>
+
+### Step 1: Create an OAuth 2.0 App in Atlassian
+
+1. Go to [developer.atlassian.com/console/myapps](https://developer.atlassian.com/console/myapps/) and click **Create** > **OAuth 2.0 integration**
+2. Under **Authorization**, add a callback URL:
+   - Local: `http://localhost:7091/api/connectors/callback?provider=confluence`
+   - Production: `https://yourdomain.com/api/connectors/callback?provider=confluence`
+
+### Step 2: Configure Permissions
+
+In your app settings, go to **Permissions** and add the **Confluence API**. Enable these scopes:
+- `read:page:confluence`
+- `read:space:confluence`
+- `read:attachment:confluence`
+
+### Step 3: Get Your Credentials
+
+Go to **Settings** in your app to find the **Client ID** and **Secret**. Copy both.
+
+### Step 4: Configure Environment Variables
+
+Add to your backend `.env` file:
+
+```env
+CONFLUENCE_CLIENT_ID=your-atlassian-client-id
+CONFLUENCE_CLIENT_SECRET=your-atlassian-client-secret
+```
+
+Add to your frontend `.env` file:
+
+```env
+VITE_CONFLUENCE_CLIENT_ID=your-atlassian-client-id
+```
+
+| Variable | Description | Required |
+|----------|-------------|----------|
+| `CONFLUENCE_CLIENT_ID` | Client ID from your Atlassian OAuth app | Yes |
+| `CONFLUENCE_CLIENT_SECRET` | Client secret from your Atlassian OAuth app | Yes |
+| `VITE_CONFLUENCE_CLIENT_ID` | Same Client ID, used by the frontend to show the Confluence option | Yes |
+
+### Step 5: Restart and Use
+
+Restart your application, then go to the upload section in DocsGPT and select **Confluence** as the source. You'll be redirected to Atlassian to sign in, then can browse spaces and select pages to process.
+
+</Steps>
+
+## Troubleshooting
+
+- **Option not appearing** — Verify `VITE_CONFLUENCE_CLIENT_ID` is set in the frontend `.env`, then restart.
+- **Authentication failed** — Check that the callback URL matches exactly, including `?provider=confluence`.
+- **No accessible sites** — Ensure the authenticating user has access to at least one Confluence Cloud site.
+- **Permission denied** — Verify that the Confluence API scopes are enabled in your Atlassian app settings.

-- Check that `VITE_GOOGLE_CLIENT_ID` environment variable is present in your frontend configuration
-- Check browser console for any JavaScript errors
-- Ensure the frontend has been restarted after adding environment variables
-
-**"Authentication failed"**
-- Verify that your OAuth 2.0 credentials are correctly configured
-- Check that the redirect URI `http://<your-domain>/api/connectors/callback?provider=google_drive` is correctly added in GCP console
-- Ensure the Google Drive API is enabled in your GCP project
-
-**"Permission denied" errors**
-- Verify that the OAuth consent screen is properly configured
-- Check that your Google account has access to the files you're trying to select
-- Ensure the required scopes are granted during authentication
-
-**"Files not processing"**
-- Check that the backend environment variables are correctly set
-- Verify that the OAuth credentials have the necessary permissions
-- Check the backend logs for any error messages
-
-### Environment Variable Checklist
-
-**Backend (.env in root directory):**
-- ✅ `GOOGLE_CLIENT_ID`
-- ✅ `GOOGLE_CLIENT_SECRET`
-
-**Frontend (.env in frontend directory):**
-- ✅ `VITE_GOOGLE_CLIENT_ID`
-
-### Security Considerations
-
-- Keep your Google Client Secret secure and never expose it in frontend code
-- Regularly rotate your OAuth credentials
-- Use HTTPS in production to protect authentication tokens
-- Ensure proper OAuth consent screen configuration for production use
+- **Option not appearing** — Verify `VITE_GOOGLE_CLIENT_ID` is set in the frontend `.env`, then restart.
+- **Authentication failed** — Check that the redirect URI matches exactly, including `?provider=google_drive`. Ensure the Google Drive API is enabled.
+- **Permission denied** — Verify the OAuth consent screen is configured and the user has access to the target files.
+- **Files not processing** — Check backend logs and verify that backend environment variables are correctly set.
 
 <Callout type="tip" emoji="💡">
-For production deployments, make sure to add your actual domain to the OAuth consent screen and authorized origins/redirect URIs.

+"""Backfill DocsGPT's Postgres user-data tables from MongoDB.
+
+One script for every migrated collection. Adding a new collection is a
+two-step change in this file:
+
+1. Write a ``_backfill_<name>`` function that takes keyword args
+   ``conn``, ``mongo_db``, ``batch_size``, ``dry_run`` and returns a
+   stats ``dict``.
+2. Add a single entry to :data:`BACKFILLERS`.
+
+There are intentionally no per-collection CLI flags or environment
+variables — ``USE_POSTGRES`` in ``.env`` is the only knob operators
+need during the migration window. This script discovers what's available from
+the :data:`BACKFILLERS` registry and runs whichever tables were asked for.
+
+Usage::
+
+    python scripts/db/backfill.py                     # every registered table
+    python scripts/db/backfill.py --tables users     # only specific tables
+    python scripts/db/backfill.py --dry-run          # count without writing
+    python scripts/db/backfill.py --batch 1000       # tune commit size
+
+Exit codes:
+    0 — every requested table completed successfully
+    1 — misconfiguration (missing env var, unknown table name)
+    2 — at least one table failed at runtime (others may still have succeeded)
