It's not really fine, because the only info you see about the result
type is "record", which is less detail than you should get (or be able
to get, anyway --- perhaps only \df+ need show the OUT parameters).
A related gripe is that \df doesn't show parameter names, which is a
pretty big loss from a documentation standpoint.
The hard part is fitting all that info into a tabular display.
\df output already tends to exceed the width of a terminal window ...
