+      The <command>CREATE TABLESPACE</> command records the location of the
+      tablespace in WAL. This could be a problem if the WAL segments are
+      replayed on a different system to those that they were created on because
+      it is likely that the tablespace directory will not exist on the second
+      system. To avoid this, you should ensure that the path to the tablespace
+      exists on the secondary machine and has the correct permissions.
