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. ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
