No objection to clean up this at the same time. + <varlistentry> + <term><option>-f <replaceable>filenode</replaceable></option></term> + <term><option>--filenode=<replaceable>filenode</replaceable></option></term> + <listitem> + <para> + Only validate checksums in the relation with specified relation file node. + </para> Two nits. I would just have been careful about the number of characters in the line within the <para> markup. And we use extensively "filenode" in the docs. So the description would become as follows: Only validate checksums in the relation with filenode <replaceable>filenode</replaceable>. + [ 'pg_checksums', '--enable', '-filenode', '1234', '-D', $pgdata ], This fails, but not for the reason it is written for. It looks strange to not order --filenode alphabetically in --help. With all these issues cleaned up, I got the attached. Does that look fine? (I ran pgperltidy and pgindent on top of it.) -- Michael
