Get the number of records of a result set

[Eugenio Tacchini <eugenio.tacchini@xxxxxxxx>]

Hello,
I'm writing a function in PL/pgSQL and I would like to know if there 
is a method to get the number of records in a result set, after a 
select query, without executing the same query using COUNT(*).

Thanks.

Regards,

Eugenio.
