+        For reliable recovery when changing a cluster from
+        <varname>fsync</varname> off to on, it is necessary to force all
+        modified buffers in the kernel to durable storage.  This can be
+        done while the cluster is shutdown or while fsync is on by running
+        <command>initdb --sync-only</command>, running <command>sync</>,
+        unmounting the file system, or rebooting the server.
