missing FROM clause ?

Hello.
In Postgres 8.1 I have a message that there is a missing FROM clause in the following query:
 
select into l_validity "rok_valjanosti"."rok_valjanosti" FROM ( SELECT min("rok_valjanosti"."rv_id") AS "rv_id", "rok_valjanosti"."rok_valjanosti" FROM "rok_valjanosti" GROUP BY "rok_valjanosti"."rv_id", "rok_valjanosti"."rok_valjanosti") sve;
If I change parameter "add missing from" in postgresl.conf to "on" than it works...
I would like to include FROM clause, but can't see where.
 
Thanks,
 
Zlatko

That subquery is called "sve" so I think you meant
   SELECT INTO l_validity svw.rok_valjanosti FROM ...
