Note that this is a follow-up on these Stack Overflow questions, which
received no response at the time they were posted:

http://askubuntu.com/questions/634796/two-factor-authentication-with-password-and-usb-device-for-postgresql-server

http://stackoverflow.com/questions/31984222/create-a-login-role-for-postgres-using-pam-madule

I haven't done much with PAM-USB and PAM integration, so I don't think
I can offer much help, at least not quickly.
