While I agree that the PGDATA directory shouldn't be used by anything
save postgres, I don't think that lost+found constitutes another use of
the directory.  The only way that a conflict could occur is if postgres
used the lost+found directory, something I that don't expect will occur.

Side note, the reason that I ran into this in the first place is because
I'm toying with multiple data directories each on their own logical volume.
For the directory structure I'd prefer something like postgres/data[123]
rather than postgres/data[123]/data or postgres[123]/data.
