This patch is tracked with this entry in the commit fest app and is
marked as "Ready for committer". Hence I am moving this specific part
to 2014-12 to keep track of it:

Based on those comments, I am marking this entry as returned with feedback:
https://commitfest.postgresql.org/action/patch_view?id=1367
Heikki has sent as well a new patch to use a binary heap method
instead of the red-black tree here:
http://www.postgresql.org/message-id/54886BB8.9040000@vmware.com
IMO this last patch should be added in the CF app, that's not the case now.
