Sorry, it was not clear from my message.

I meant that I had success creating a table as a result of multiple
invocation of foo (parameter) using the result of an "outer" query as
list of parameter to foo, only if foo () is a "normal" function,
returning a simple value.

It was a misleading sentence anyway, since what i'm asking help for is
the case where foo () is a SRF and returns more than 1 row.

What i'm trying to do is a query where i get a result of this kind

a | b | c
--+---+---
1 | 2 | 3     
5 | 9 | 1
4 | 0 | 0 
2 | 0 | 0
0 | 0 | 0 

given that i select from the table Anagrafica the fields 'aaa' and
'bbb', where the first 2 rows obtained as the result of foo ('aaa') and
the latter 3 as the result of foo ('bbb').

Thanks a lot for help !

PS: Sorry for late answering, i had problems with mail.
