FWIW, I tried this on Fedora Core 6 while running pgbench:
[tgl@rh2 ~]$ tar --version
tar (GNU tar) 1.15.1
[tgl@rh2 ~]$ tar cf t.tar $PGDATA
tar: Removing leading `/' from member names
tar: /home/tgl/testversion/data/pg_xlog/000000010000000000000003: file changed as we read it
[tgl@rh2 ~]$ echo $?
0
[tgl@rh2 ~]$
ISTR that the original caution was against writing scripts that assume
anything being emitted to stderr must indicate a problem.
