Yeah, currently composites and arrays only support binary results in libpqtypes. This forces any array elementType or any member of a composite to have a send/recv routine. Using the "fallback to text output" approach, this limitation on array elements and composite members would be removed.
Actually, I am confusing the way the protocol handles arrays and composites (as a single column value, vs. the way libpqtypes handles these (as a separate result object). for instance, the members of a composite inherit the format of the column within the protocol. To allow one member of a composite to be text formatted and another be binary, would require a change to the protocol, an additional format value per member header.
