No, you need to use a FROM clause if you wish to update based on another table.
Taking the example from that page you linked to:
UPDATE tableone
SET field1 = tabletwo.fieldx
FROM tabletwo
WHERE tableone.commonid = tabletwo.commonid;
Look at http://www.postgresql.org/docs/current/static/sql-update.html
for more information.
