I have two different machines that run pg_dump in a batch file. One prompts for a password and the other one does not. I am running version 8.1 on Windows XP. Both machines have a pgpass.conf file in the right place. The Administrator user runs the batch file. How do I get pg_dump to run without prompting for a password?
