> AGG_MEM_CORRELATION_FACTOR has valid value between 0.0 to 1.0. This query
> option name can be misinterpreted as high value means highly correlated
> columns, but it is actually the opposite in the code implementation. 1.0 is
> interpreted as no correlation at all in the code, while <1.0 means somewhat
> correlated. Documentation should be clarified about this.
