With a behavior similar to the in-core log_parameter_max_length, this
looks rather sane to me. This is consistent with the assumptions of
errdetail_params().

+$node->append_conf('postgresql.conf', "auto_explain.log_parameter_max_length = -1");
Nit. You don't need this change in the TAP test, as this is the
default value to log everything.
