Compiling Stored Procedure - Mailing list pgsql-novice

Hi all,

    I'm new in postgre and I'm using the 8.1 version.
    I need do some [Stored] Procedure in the Database to gain more
performance in some queries execution. However, these SPs must be
compiled.
    Some SPs is already created in plpgsql. Is it possible compile
them? If not, how can I do that?

    I read about write functions in C, but I didn't found functions
using sql statements...

Thanks.
Danilo
