Need an example - more information - Mailing list pgsql-interfaces

The function should run on the server (installed with CREATe FUNCTION
command) as in the example :

select product, price, getcomplexinformation(product) from stock;

The getcomplexinformation function will search over other 3 tables,
compute some intense math operations on them and return a result. I have
experimented with plpgsql and pltcl but I will need more speed.

Thanks again,
