+1 except that it would be a \set variable for consistency with the
other execution-controlling variables. \pset variables control only
the display.

BTW if we wanted to auto-detect that a query requires binding or the
extended query protocol, we need to keep in mind that for instance
"PREPARE stmt AS $1" must pass without binding, with both the simple
and the extended query protocol.
