velioglu 78e6d990a2 Fix master plan of the query with distinct, aggregate and group by clauses. ... Before this PR, we were trusting on the columns of group by about guaranteeing the uniqueness of the results. However, this assumption is correct only if the columns in the group by is subset of columns in the distinct clause. It can be wrong if we have part of group by columns and some aggregation columns in the distinct clause. With this PR, we add distinct plan on top of aggregate plan when necessary.		2018-02-26 15:30:15 +03:00
