It's currently open.  It's on my to-do list, but since PG 8.3 is still
just barely out of RC it isn't a high priority.  We certainly wouldn't
turn down a patch, though!

The query is looking for every node /but/ the root node, so I think  a
variation on { parent_ou => { '!=' => undef } } is what we'll want.
Of course, the Class::DBI docs don't mention that spell for "is not
null", so an alternative is to filter the return of your modification
where the parent_ou field is not undef.

Thanks, though your instincts were correct.  Generally if you're
getting an undefined variable error then there's a bigger problem
somewhere.  I'll look at these in terms of beefing up the error

For testing, and for stability's sake (more than just tsearch changes
...), I'd suggest sticking with 8.2 for now.

Sending patches here is fine, but as attachments and as svn diffs
would ease things a little on this end ... I may need to update the
docs to be more explicit about that.

Thanks, Reuben!
