adding missing FROM-clause entry for table

I'm getting a notice for a query:

adding missing FROM-clause entry for table "promomodel"

The query is:

SELECT PromoModelID
FROM PromoModel, Model
LEFT JOIN Supplier ON Supplier.SupplierID = PromoModel.SupplierID

The notice doesn't appear if I switch the two tables names in the FROM clause:

SELECT PromoModelID
FROM Model, PromoModel
LEFT JOIN Supplier ON Supplier.SupplierID = PromoModel.SupplierID

As I understand it, the order of tables shouldn't matter, so I must be missing something. Could someone fill me in please? (Redhat 7.1, Postgres 7.4beta)
