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Oh, wait, nevermind, it was revoked and reworked: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 new patch?

I'm confused.

As far as I can see, Simon stated that he would revert it but never did so.

Perhaps we should go do that...

The patch is definitely still in the tree. Given the dangling-pointer
concerns raised by Heikki, I think we had better revert it before
shipping 9.1. Also, the entry in the September commitfest can be marked
"returned with feedback", since it clearly predates the discussion on
-hackers.

It's not a 9.1 patch, so that is not a concern.

I'm back now and will act as advertised.

I've revoked the performance aspect. The difference between release
and commit has been maintained since it makes the code easier to
understand.
