Hmm:

#   Failed test 'corrupt backup fails verification: extra_file: matches'
#   at t/003_corruption.pl line 198.
#                   'pg_verifybackup: error: pax extensions to tar format are not supported

Apparently its version of "tar" will produce pax-extended files
at the drop of a hat.  I have an OpenSUSE image around here
somewhere, will see if I can reproduce this.  But while I'm
asking, what filesystem are those animals running on top of?
