You don't show what you did to get this error, but I'd guess you
called the function like this:
SELECT article_display(10, 0); -- wrong
You should have called it like this:
SELECT * FROM article_display(10, 0);
The function as posted has a few other problems, like returning the
wrong type (you return a RECORD variable instead of an article_output
variable) and not selecting enough columns for the declared return
type. The return type also doesn't match the type shown in the
CREATE TYPE statement, and the CREATE TYPE statement fails with a
syntax error due to a missing comma. As I mentioned previously,
please post the *exact* code you're running so typographic errors
in the message don't distract from the real problem. Those typos
prevent people from loading the code into their own database so
they can test it unless they correct the mistakes, and then they
can't be sure they're running the same thing you are.
