I suppose that's meant to be backwards-compatible with the current
behavior:
regression=# \timing foo
unrecognized value "foo" for "\timing"; assuming "on"
Timing is on.
but I agree that if we're changing things in this area, that would
be high on my list of things to change. I think what we want going
forward is to disallow setting "special" variables to invalid values,
and that should hold both for regular variables that have special
behaviors, and for the special-syntax cases like \timing.
