Just FYI, preferred style for the second line would be
label = DatumGetCString(labelDatum);
Nearly all standard data types have DatumGetFoo and FooGetDatum
macros to hide the conversion details (even if it's only a cast).
the clean version:
--------------------------------------------------------------
#include "utils/builtins.h"
PG_FUNCTION_INFO_V1(esterna_nome);
Datum esterna_nome(PG_FUNCTION_ARGS){
Datum datumIbrido = PG_GETARG_DATUM(0);
Datum labelDatum;
char *label;
labelDatum = DirectFunctionCall1(enum_out,datumIbrido);
label = DatumGetCString(labelDatum);
if(strcmp(label,("label_constant"))==0){
...
}
...
}
--------------------------------------------------------------
thank you again!
