+  - Use the [direct connection](https://supabase.com/docs/guides/database/connecting-to-postgres#direct-connection) URL, which Supabase lists for `pg_dump`. It should look similar to this:
+  ```text
+  postgresql://postgres:[YOUR-PASSWORD]@db.[PROJECT-REF].supabase.co:5432/postgres
+  ```
+  - Direct connections use IPv6 unless the project has the IPv4 add-on. If your network can't reach one, use the [shared pooler in session mode](https://supabase.com/docs/guides/database/connecting-to-postgres#pooler-session-mode) instead:
   ```text
-  postgres://postgres.apbkobhfnmcqqzqeeqss:[YOUR-PASSWORD]@aws-0-ca-central-1.pooler.supabase.com:5432/postgres
+  postgresql://postgres.[PROJECT-REF]:[YOUR-PASSWORD]@[POOLER-HOST]:5432/postgres
   ```
