I like it. It makes my code even simpler, and it allows using all the
different \g variants transparently. See attached patch.

Right, the end-bind isn't needed.
Btw., this also allows doing things like
SELECT $1, $2
\bind '1' '2' \g
\bind '3' '4' \g
This isn't a prepared statement being reused, but it relies on the fact
that psql \g with an empty query buffer resends the previous query.
Still kind of neat.
