In this case, I think you can use log_error_verbosity = terse which
excludes the logging of DETAIL, HINT, QUERY, and CONTEXT error
information. On the other hand, since actually the log of particular
large SQL or its parameter sometimes presses the free capacity,
possibly it's a good idea to have such threshold.
