Would it be too far off to guess that you're running Gentoo? This looks
like ye olde problem with that hierarchical-queries patch that they push
on people. Either adding or removing the patch breaks your database :-(.
Since your rewrite rule looks standard, I'm guessing that you rebuilt
and added the patch at some point after initially building your database.
Reconfigure 8.0 the way you originally built it and you should be OK ...
unless you have views that you created after changing ...
