+[node-postgres](https://node-postgres.com/) driver for Vulcan SQL.
+
+## Install
+
+1. Install package
+
+   ```sql
+   npm i @vulcan-sql/extension-driver-pg
+   ```
+
+2. Update `vulcan.yaml`, enable the extension.
+
+   ```yaml
+   extensions:
+     pg: '@vulcan-sql/extension-driver-pg'
+   ```
+
+3. Create a new profile in `profiles.yaml` or in your profiles' paths.
+
+   ```yaml
+   - name: pg # profile name
+     type: pg
+     connection:
+      # Optional: The max rows we should fetch once.
+      chunkSize: 100
