Removing -log_min_messages =3D 'debug2' -log_error_verbosity =3D verbose not only reduces 035's log output volume from 1.6MB to 260kB, but also speeds it up nontrivially: on my machine it takes about 8.50 sec as of HEAD, but 8.09 sec after silencing the extra logging. So I definitely want to see that out of there. regards, tom lane
