It looks to me like Robert added that item to the "open items" page,
but he put it at the bottom --- ie in the "already resolved items"
list:

https://wiki.postgresql.org/index.php?title=PostgreSQL_9.4_Open_Items&diff=22417&oldid=22380

Probably this was a mistake and it should have gone into the still-to-do
list.
