There are also some useful examples in contrib/.  Several contrib
modules have macros like

#define _textin(str) DirectFunctionCall1(textin, CStringGetDatum(str))

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

which work pretty much the same as the old textin() and textout()
functions did.
