pg access links to another postgresdatabase

A newbie question:

Is it correct to conclude that the Forms, Reports, Queries that
PgAccess stores in database A can not refer to Queries, and Tables
in another PostgresQL database ?
( e.g. MS Access links to other tables from the *mdb that stores the reports
forms can module code).

Is there a example / sample application to see how all this works?
