Description
Using the latest django code from subversion (revision 10645), when I have autocommit set to True in my settings.py, it looks like the isolation_level of the connection is never being set to 0. 3460_r10645-autocommit.diff patch seems to fix the problem, but I don't know if it's the right way to fix it.

looks sane. Test suite passed with autocommit enabled (postgres 8.3). Would be nice to have a buildbot that checks autocommit mode since it probably won't get much testing attention.

I'm not sure this is RFC; I want to look closer first.

I believe this is correct - the problem is that the call to "self.connection._set_isolation_level(int(not autocommit))" in "DatabaseWrapper._init_()" is made before "self.connection" exists.
An alternative approach might be to move this entire call from "DatabaseWrapper._init_()" to the location highlighted in this patch.
Looking historically, this appears to have got broken when #3460 was applied, between the final patch on the ticket (http://code.djangoproject.com/attachment/ticket/3460/3640_r9736-autocommit-safe.diff) and the commit r10029.
The autocommit feature is in the Version1.1Features list, and is fundamentally broken without this fix, so I'm tagging this ticket to 1.1.
