Ok, I found the solution :-D
In the function test(), instead of:
SELECT INTO r get_id(''mytable'');
The following must be done:
SELECT INTO r * FROM get_id(''mytable'') AS (id INT, name VARCHAR(50));
/!\ the datatypes must be EXACTLY the same.
For example, specifying CHARACTER VARYING or even VARCHAR(51) instead of
VARCHAR(50) will lead to the following error:
ERROR: query-specified return row and actual function return row do not
match
I hope it will at least help some one...
