Yes, I have same user name on my linux box and postgresql,
and they have same password (now).

Finally, by my small program, I found the PAM module is attempting
to read /etc/shadow to authenticate, but /etc/shadow can't be read
by non-superuser privilege.
I know, the postmaster is running under "postgres" user privilege,
so PAM auth will always cause 'permission denied' around /etc/shadow.
How can I solve this? Any ideas?
Thanks.
