another thing i tried to do was:
create or replace function lafecha(timestamp with time zone) returns date
as 'select date($1);'
language 'SQL'
with iscachable;
But i got the message: ERROR parser: parse error at or near "iscachable";
if avoid "with iscachable" string the fucntion was created succesfully.
