@@ -10,7 +10,8 @@ How you connect to your database depends on where you're connecting from:
 
 - For frontend applications, use the [Data API](#data-apis-and-client-libraries)
 - For Postgres clients, use a connection string
-  - For persistent clients (for example, long-running servers or database GUIs) use the [direct connection string](#direct-connection) if your environment supports IPv6, and [Supavisor session mode](#supavisor-session-mode) if not
+  - For single sessions (for example, database GUIs) or Postgres native commands (for example, using client applications like [pg_dump](https://www.postgresql.org/docs/current/app-pgdump.html) or specifying connections for [replication](/docs/guides/database/postgres/setup-replication-external)) use the [direct connection string](#direct-connection) if your environment supports IPv6
+  - For persistent clients, and support for both IPv4 and IPv6, use [Supavisor session mode](#supavisor-session-mode)
   - For temporary clients (for example, serverless or edge functions) use [Supavisor transaction mode](#supavisor-transaction-mode)
