I don't think it can either, which kind of makes sense. Tar is an archiving
utility to create an archive of files; not to create an archive of the
contents of files. Subtle difference, but makes sense. If I created a tar
archive from the stream coming out of tar, what would be listed when I did
'tar tvf /dev/st0'?

I think I'll hack the backup to output it to a temp file, then tar that file
to tape.

At the very least:

#!/bin/bash

$DBNAME='dbname'
$TMPFILE="/tmp/$DBNAME.date.sql"
$TAPE_DRIVE='/dev/st0'

/usr/local/bin/pg_dump $DBNAME > $TMPFILE
/bin/tar cvf $TAPE_DRIVE --label="$TMPFILE" $TMPFILE
/bin/rm -f $TMPFILE
