SETOF anyelement - get_call_result_type

Hi all,

I'm trying from a C function to return a SETOF anyelement,
but get_call_result_type(fcinfo, NULL, &tupdesc)
don't return TYPEFUNC_COMPOSITE  as expected.

Something i've missed ?

(I know i can do it with a SETOF RECORD instead,
but it leads to explicitely define the output type of each column
and i want to avoid this, if possible.)


Thanks in advance,
