median.diff (application/octet-stream) patch

Hello,

there is updated version - with support of window clause. The limits
are work_mem for using inside window aggregate or unlimited when it is
used as standard query.

This patch needs a few work - can share a compare functionality with
tuplesort.c, but I would to verify a concept now.

Comments?

Regards

Pavel
