Right. This is nearly the same, perhaps could be made actually the
same, as a fast-path function call.
The existing FPF call mechanism only supports binary data, but I think
it would be useful to allow either binary data or ASCII data in both FPF
and prepared-statement cases. The ASCII path would require invoking a
datatype's conversion function on the backend side, but you'd still get
to skip the SQL statement parsing/planning overhead.
(Wanders away wondering whether COPY might not be made to fit into this
same mold...)
