I’m not accepting this line of work as part of this patch. Please limit
this to the merits of choosing \N as the particular value for \pset null on
this page. You can start a new thread regarding a policy change for
marking up null values in the whole of the documentation. But as Tom said,
I don’t see that going anywhere.
