Hello,

I have a problem with the output value of a function, that is to say,
the value I get when the function is carried out:
I want a function, chich output value is an array, and when I create the
function, it is defined as follows:

> create function path_inte(path,path) returns _point
>  as '/net/ipfy/angel/postgres/geometry/libMWgeom.so' language 'c';
>
>  When the function is used, the resultat is always: "{}", so I do not
> Know if:

-the function is not well defined, or
-the output value can not be an array

Thank you very much.
