Patch by okbobcz on 2010-08-19 06:01:51 AM: Initial version.
Comment by umitanuki on 2010-09-19 10:13:53 PM: The type of returned value, window function call and the second argument of percentile should be reconsidered. It doesn't contain any of tests and docs.
Patch by okbobcz on 2010-09-23 07:58:29 AM: moved to core, fixed, percentile aggregate removed
Comment by umitanuki on 2010-10-01 02:45:35 AM: confirmed issues are fixed. The memsort should actually be implemented modifying tuplesort.
Patch by umitanuki on 2010-10-03 08:33:29 AM: We reject median call in window aggregate.
