While rebasing, I realized this should have bumped XLOG_PAGE_MAGIC.

Also, there's a dangling "and".

+        The supported methods are <literal>pglz</literal>,
+        <literal>lz4</literal> (if <productname>PostgreSQL</productname>
+        was compiled with <option>--with-lz4</option>) and
+        <literal>zstd</literal> (if <productname>PostgreSQL</productname>
+        was compiled with <option>--with-zstd</option>) and
+        The default value is <literal>off</literal>.
+        Only superusers can change this setting.
