What I'd like would be to have it sorted by activity, showing first the
thread which received the later messages. I'm yet to play with CTE and
window function myself so without a database example to play with I
won't come up with a nice query, but I guess a more educated reader will
solve this without a sweat, as it looks easier than sudoku-solving,
which has been done already :)
