Cool, I would love to get rid all of them, like I proposed on [1].
When I finalize the examples I'm probably going to \pset null <NULL>.
Yes, much better than an empty space in the examples, but you need to show what PSET you did, maybe
<literal>\pset null</literal> meta-command</link> to specify the textual output of null values it encounters in query results. To get same results as you are seeing on this page, do "\pset null <NULL>"
typo in func.sgml
<link linkend="nullvalues">three-valued</link> typed results (true, false, or null).
should remove that comma, right ?
results (true, false or null).
Would be good to mention on nullvalues-json section that nulls on JSON values are case sensitive, so NULL or Null won't work
