You can't access another database even inside 1 server directly. Find something about contrib/dblink - maybe it will help you. Regards, Tomasz Myrta
you should install dblink as Tomasz said. To do that: cd ...../postgresql-7.3.2/contrib/dblink gmake gmake install then you enter into psql to create the functions: \i dblink.psql then you try (change the params): SELECT * FROM dblink('host=localhost port=5432 dbname=franco user=admin password=1234', 'SELECT id, name FROM people') AS (id INTEGER, people TEXT); If you skip the values host, port, ..., the defaults will be used. If it works in psql, it should work inside a function.
