Hello,

To have something operational you have to know quite a bit of psql
details (:-substitutions, backslash command logic, gset, if, quit...).
Thus short, simple but meaningful examples which show how to do something
useful with all that in the documentation may help people take advantage
of these new features.
Given my experience with "\d*", I'm not sure I would assume that a new
psql feature would work with older servers.
