You get that as root? I think you've got filesystem problems that are
beyond the ken of us mere database weenies. Better ask some kernel
hackers.

(If you're on a SELinux-enabled system it might have to do with SELinux
permissions, although I thought that those typically weren't enforced
against interactive shells. It might be useful to look in the kernel
log and see if anything comes out when you do this.)

If it won't let you chown it, it likely won't let you rm it, either...
