Yep, there is no other better solutions except sorting result sets, but the
important thing is how?
Firstly how to rewrite those sytaxes, e.g. `AVG(DISTINCT col)`, rewrite it
to `DISTINCT col` or not?
Secondly how to sort those result sets to calcuate aggregation results of
distinct columns,
Would you list some examples to share the "new ideas"? I couldn't find
other solutions besides sorting result sets.

Hi, all
New year, new start.
The code refactoring of merging the data generated by `DISTINCT` syntax is
also on the way.
I decided to do this for i got some new ideas about this module
implementation so as to make its implementation easier to extend in the
next stage and clearer to understand.
