I'd have thought a very long line would be more likely to trigger internal performance problems than the original. What happens if you read the file with "psql -f dump.sql" instead of cat/stdin? BTW, I get flat times for your psql test case on Unix, again both with local and remote client. So whatever is going on here, it's Windows-specific. regards, tom lane
