{OT?] Auth_PG_grp_group_field directive gives parameter error

I've sent an e-mail to Guiseppe Tanzilli about this, but maybe someone
here has seen this. I'm pretty sure it's not PostGreSQL, but it is
tangential.

We are updating to mod_auth_pgsql2 v2.0.latest and apache 2.0.latest, in
the process of updating to PostGreSQL 7.4.latest.

We get the following error:

> Auth_PG_grp_group_field takes one argument, the name of the group-name field.

on the directive

    Auth_PG_grp_group_field rid

These are the directives we are using:

   Auth_PG_host 127.0.0.1
    Auth_PG_port 5432
    Auth_PG_database apache_auth
    Auth_PG_user postgres
    Auth_PG_pwd postgres
    Auth_PG_pwd_table user_bbs
    Auth_PG_uid_field uid
    Auth_PG_pwd_field pw
    Auth_PG_grp_table user_bbs
#    Auth_PG_gid_field rid               # name change from 2.0.0
    Auth_PG_grp_group_field rid        # Auth_PG_gid_field -> Auth_PG_grp_group_field
    Auth_PG_grp_user_field uid          # works from 2.0.0
#    Auth_PG_grp_whereclause " and rid = 'bbs@tekitou' "
    Auth_PG_encrypted on
    Auth_PG_hash_type MD5
    AuthName "Please Enter Your Password"
    AuthType Basic
    <Limit POST GET>
        require valid-user
        require group bbs@tekitou
    </Limit>

(And, yes, I'll also try an apache mailing list.)

Apologies in advance if the noise is not appreciated.
