If it's OK to be off by one, then the query above is fine. But if you need the exact median, then you will have trouble. For example, for the sequence (1,3,5,7) the median is 4 but the query above returns 3. For (1,2,3,503,603,703) the median is 258 but the query above returns 503.

You could fix the flaw of imprecision by taking max and min of each quartile in a subquery, then AVGing the MAX of the previous and MIN of the next?
