Removing

-log_min_messages = 'debug2'
-log_error_verbosity = 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.
