Unfortunatly, I don't think type input/output functions can be written
in anything other than C. IIRC, no other PL understands the cstring type.

As for why, well, because nobody has done the legwork yet. Oh yes, type
input/output functions are also called at various points, including
during parsing where there is no current snapshot. Whether the PLs are
affected by this I don't know, but you cannot do SPI at that point.

Hope this helps,
