Yes, I agree, but also in cursor page.
Talking about cursor I can't find example that shows how pass a bounded cursor to a function or procedure (must be already open? must be declared in some specific way?)

That is not supported. Parameters can only be used in a place where constants
(SQL literals) might appear, not instead of identifiers (names of tables, columns etc.)
I looked, and that is really not documented anywhere.
One of PREPARE or the extended query protocol might be good places.
