Remove all the rows in a result set with the highest value for column $column unless the number of rows is less $limit.
This returns the new array of rows and the highest value of column $column for the rows left. The ordering of rows is maintained.
This is useful for paging on mostly-unique values that may sometimes have large clumps of identical values. It should be safe to do the next query on items with a value higher than the highest of the rows returned here. If this returns an empty array for a non-empty query result, then all the rows had the same column value and the query should be repeated with a higher LIMIT.
