Tom, I would appreciate if you could answer this question.

For me, the current behavior is both stupid and irritating: why would pg 
decide to drop the result of a query that I carefully typed?. It makes the 
multi-query feature basically useless from psql, so I did not resurrect 
the guc, but I will if it would remove a veto.

In the meantime, here is a v9 which also fixes the behavior when using 
\watch, so that now one can issue several \;-separated queries and have 
their progress shown. I just needed that a few days ago and was 
disappointed but unsurprised that it did not work.

Watch does not seem to be tested anywhere, I kept it that way. Sigh.
