The best way to get from a C string to a valid datum is to invoke the
datatype's input conversion routine. If you know you want text,
you could do
#define _textin(str) DirectFunctionCall1

And you are trying to assign this datum to what kind of column?
(Hint: there isn't any kind for which a plain C string is valid data.)

Hm. Looks like the author of SPI_modifytuple

heap_formtuple is for constructing a tuple from scratch. It sounds like
you should be using heap_modifytuple instead.
