One interesting artifact of using \e to edit a multi-line command is
that the same command is then treated as a single-line command in
subsequent up-arrow or Ctrl-P attempts.
I use this frequently to achieve a similar effect to what you're after.
The one downside is that if you leave the psql session, it's returned
to multi-line format in the psql history.
