If you can dd the file onto your tape drive, then it's some weird
interaction between pg_dump and your system I'd think.  Could the be
some maximum size that you can buffer through pipes / redirects on
your machine?

I'd test to see if cat pgdumpfile.sql > /dev/st0 works or not.  If it
fails at the same approximate size, then it's something to do with
redirection.  If tar works but redirects fail, then the problem isn't
with postgresql.  i.e. do something similar to what you're doing with
pgsql and see which things fail and which ones don't.
