Unfortunately, the prompts for your username and password come out
on standard output, which you're redirecting to the file. So you
don't see them. But pg_dump is listening; type in your username and
password as if you *had* seen the prompts and it will all work.
Alternatively, you can use "echo" to give them:
echo -n -e "username\npassword\n" | pg_dump -u -v dbname > dbname.pgdump
This is insecure, as your password is briefly visible in a full ps output,
but it works non-interactively, so you can do it in scripts (e.g., from
cron). Of course, that's potentially even more insecure...
