Better dont do that but use the FROM clause of update:

http://www.postgresql.org/docs/8.1/static/sql-update.html

e.g.

UPDATE t1
SET t1.f1='test'
FROM t2
WHERE t1.t1f2=t2.t2f2
AND t1.t1f3=t2.t2f3;

(although I bet your example is sloppy and you even want t1, t2 and t3 -
so add t3 to the FROM list as you know with SELECT)
