-        When waiting for startup, pg_ctl repeatedly
-        attempts to connect to the server.
-        When waiting for shutdown, pg_ctl waits for
-        the server to remove its PID file.
+        When waiting, pg_ctl repeatedly checks the
+        server's PID file, sleeping for a short amount
+        of time between checks.  Startup is considered complete when
+        the PID file indicates that the server is ready to
+        accept connections.  Shutdown is considered complete when the server
+        removes the PID file.
         pg_ctl returns an exit code based on the
         success of the startup or shutdown.
