[COMMITTERS] pgsql: Allow pg_dumpall to dump roles w/o user passwords

Allow pg_dumpall to dump roles w/o user passwords

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.
