    To avoid this problem, taking a new full backup after changing the checksum
-   state of the cluster using <xref linkend="app-pgchecksums"/> is
+   state of the cluster using <xref linkend="app-pgchecksums "/> is
    recommended. Otherwise, you can disable and then optionally reenable
    checksums on the directory produced by <literal>pg_combinebackup</literal>
    in order to correct the problem.
