unlogged tables

I am attempting to test this

https://commitfest.postgresql.org/action/patch_view?id=424

but I'm not sure which version of PG this should be applied to. (it would be really neat, on here:
https://commitfest.postgresql.org/action/commitfest_view?id=8
if there was a note that said, this test this stuff against git tag X or branch Y or whatever)

I got the git:

git clone git://git.postgresql.org/git/postgresql.git

downloaded the patches, and applied them ok. then did ./configure and make

after much spewage I got:

bufmgr.c: In function 'PrefetchBuffer':
bufmgr.c:126:10: error: 'struct RelationData' has no member named 'rd_istemp'
make[4]: *** [bufmgr.o] Error 1

Just to make sure everything was ok with the original, I reset:

git reset --hard HEAD^
./configure
make
and all was well.

so I tried again:
make clean
make maintainer-clean

patch -p1 < relpersistence-v1.patch
.. ok ..

but then...

$ patch -p1 < unlogged-tables-v1.patch

patching file src/backend/storage/file/fd.c
The next patch would create the file src/backend/storage/file/reinit.c,
which already exists! Assume -R? [n]

That didnt happen the first time... I'm almost positive.

Not sure what I should do now.
