This is right. libpq doesn't want to use .pgpass if its permissions are
higher than 600.

Another server? or the same one?

If the same one, it's quite right too. It cannot use the .pgpass file,
so it cannot send a password, and you can't connect.

You need to have 600 permissions flags to be able to use the .pgpass
file. This is a good thing that the libpq does for your security.
