I want a function, chich output value is an array, and when I create
thefunction, it is defined as follows:
create function path_inte(path,path) returns _pointas '/net/ipfy/angel/postgres/geometry/libMWgeom.so' language 'c';
When the function is used, the resultat is always: "{}", so I do notKnow if:
-the function is not well defined, or
-the output value can not be an array
I have received your response about how a function, which output value
is an array, can be created (e-mail 10.04.99), but I get always the same
resultat. Would you be so kind as to write an example of a function,
which output value is an array ?
Thank you very much.
