Help with 9.5 feature wiki page

Hi all,

I've written a "What's new in PostgreSQL 9.5" page on the wiki, but
I'd like some help.

https://wiki.postgresql.org/wiki/What%27s_new_in_PostgreSQL_9.5

As you can see, there's some sections without content yet, and the
rest may need tidy-up, simplifying, clarifying or correcting.

So if anyone's up for helping out, please follow the link above and go edit.

Thanks

Thom
