people like me whose memory occasionally goes awry.
No objection in principle, but what are we talking about exactly?
Adding some new backslash command that lists all the variables that have
special meanings?

That's a pretty good idea, especially if we give that command a command line option too, so something like

   psql --special-variables

would run that command and exit.

Maybe I'm over-egging the pudding a bit ;-)
