savepoint commit performance

This patch:

https://commitfest.postgresql.org/action/patch_view?id=605

Seems to have been after thoughts, and back burner stuff, and forgotten about...

Has it already been commit?

http://archives.postgresql.org/pgsql-committers/2011-07/msg00206.php

Oh, wait, nevermind, it was revoked and reworked:

http://archives.postgresql.org/pgsql-hackers/2011-07/msg01041.php

but that was posted Jul 19, 2011.  And the Patch linked from commitfest is Jun 6, 2011.  So is that an old patch?  Or a
newpatch?
 

I'm confused.
