I'm personally using mod_auth_pgsql against a user table with encrypted
passwords. To properly encrypt them I am using the contrib pgcrypto
module and something like

UPDATE myusertable
SET passwd = crypt('password', gen_salt('md5'))
WHERE userid = 1;

I don't believe you can use pg_shadow to authenticate against, but some
things to look at are:

- verify that the passwords are encrypted in pg_shadow.
- try changing the value of Auth_PG_hash_type to md5
