Re: use cursor in a function

In a nutshell:

Is there a way of finding out how many rows (ROW_COUNT) are in a cursor
select? If one can, is there a way of returning a RECORD containing the
refcursor and the ROW_COUNT?

So far I've only been able to get a clue from:

1) Define function
create or replace function mycur(refcursor) returns refcursor AS '
BEGIN
    open $1 for select * from abc;
    RETURN $1;
END;
' LANGUAGE 'plpgsql';

2) Call function
temporary=> select mycur('cur');
 mycur
-------
 cur
(1 row)

3) Try to find end of cursor
temporary=> move 99 from cur;
MOVE 5
