Fixed SELECT with grouping on
            BLOB columns not to return incorrect
            BLOB info. Grouping, sorting and distinct
            on BLOB columns will not yet work as
            expected (probably it will group/sort by the first 7
            characters in the BLOB). Grouping on
            formulas with a fixed string size (use
            MID() on a BLOB)
            should work.
          
            When doing a full join (no direct keys) on multiple tables
            with BLOB fields, the
            BLOB was garbage on output.
          
            Fixed DISTINCT with calculated columns.
