textout (and all the other built-in SQL functions) now have to be called
via the "new style" calling convention.  Which unfortunately is a pain
in the neck to code in bare C.  A number of modules do something like
this:

#define _textout(str) DatumGetPointer(DirectFunctionCall1(textout, PointerGetDatum(str)))

The price of progress :-(.  See the documentation for more info.
