this may be a bit nitpicking, but I find the error message "runtime
error: Query failed with the exception: std::bad_alloc" not ideal for
normal users.

Can we please have something similar to the existing error messages,
i.e. something users are already familiar with?

I'm currently thinking about the following, where "xxx" should be
replaced by the actual limit previously set via set_limits.


    } catch (const std::bad_alloc& e) {
        rlimit limit;
        result = getrlimit(RLIMIT_AS, &limit);
        ...
        error_output.runtime_error(std::string("Query exceeded memory
limit of xxx MB RAM."));
    }



Cheers,
