All three loop variables ("FOR _user") are of type text:

create or replace function gm.get_users(name)
        _user text;
        FOR _user in
                select distinct rolname from pg_roles where oid in (
                        select member from pg_auth_members where roleid in (
                                select oid from pg_roles where rolname in 
(''gm-logins'', ''gm-public'', _db)


        END LOOP;

        FOR _user in select distinct modified_by from audit.audit_fields LOOP


        END LOOP;

        FOR _user in select distinct db_user from dem.staff LOOP


        END LOOP;

This is what the 8.4 manual says about FOR LOOP variables:

        38.6.4. Looping Through Query Results

        Using a different type of FOR loop, you can iterate through the results 
of a query and manipulate that data accordingly. The
        syntax is:

        [ <<label>> ]
        FOR target IN query LOOP
        END LOOP [ label ];

        The target is a record variable, row variable, or comma-separated list 
of scalar variables.

Note the "comma-separated list of scalar variables". This
works flawlessly for me on 8.4.1 on Debian. The 8.4.1
release notes show no change regarding FOR LOOP targets:

Are you entirely sure this is PostgreSQL 8.4 ? It was a
fairly recent change.

If so, I'd suggest asking CentOS about it. It surely is
expected to work (it does work here).
