Can you provide a *complete* example? Also, what version are you using?
I tried this in 7.2.1:
test72=# create table company (id int);
CREATE
test72=# create table refs(company_id int);
CREATE
test72=# select * from company c, refs r where r.company_id=c.company.id;
ERROR: No such attribute or function 'company'
