Doc: update libpq's documentation for PQfn(). Mention specifically that you can't call aggregates, window functions, or procedures this way (the inability to call SRFs was already mentioned).
Also, the claim that PQfn doesn't support NULL arguments or results has been a lie since we invented protocol 3.0. Not sure why this text was never updated for that, but do it now.
