It looks like changing the
elements[0] = CStringGetDatum(localT1.c_str());
elements[1] = CStringGetDatum(localT2.c_str());
to:
elements[0] = PointerGetDatum(cstring_to_text(localT1.c_str()));
elements[1] = PointerGetDatum(cstring_to_text(localT2.c_str()));
Solved the problem. If anyone thinks that there is a better way please tell
me.
There is not better or worst way - you have to use just correct way, that is one
There are already prepared macros
#define CStringGetTextDatum(s) PointerGetDatum(cstring_to_text(s))
#define TextDatumGetCString(d) text_to_cstring((text *) DatumGetPointer(d))
#define TextDatumGetCString(d) text_to_cstring((text *) DatumGetPointer(d))
you can use it.
