commit    852de579a6eea3bebf719530ea2d2c232573b845

    Fix pg_waldump/t/001_basic.pl with BSD tar on ZFS.
    
    The new test fails with an error about a missing WAL file on that
    stack, because it is archived in GNU tar's --sparse --format=posix
    format.  BSD tar uses that format by default, unlike GNU tar itself, and
    ZFS triggers it by implicitly creating sparse files when it sees a lot
    of zeroes.
    
    The problem will surely also affect real users of the new tar support in
    pg_waldump (commit b15c1513) and pg_verifybackup (commit b3cf461b3) on
    such systems.  Ideas under discussion, but for now the test is made to
    pass by disabling sparse file detection in BSD tar.
