Allow pg_dumpall to dump roles w/o user passwords

Browse Source 
Add new option --no-role-passwords which dumps roles without passwords.
Since we don’t need passwords, we choose to use pg_roles in preference
to pg_authid since access may be restricted for security reasons in
some configrations.

Do not dump passwords for roles. When restored, roles will have a NULL
password and authentication will always fail until the password is reset.
Since password values aren't needed when this option is specified we
use the catalog view pg_roles in preference to pg_authid, since access
to pg_authid may be restricted by security policy.
