void psqlconn() {
  
 connection C("dbname = db user = u1 password = mypwd* \
 hostaddr = 127.0.0.1 port = 5432");
 if (C.is_open()) {
     cout << "Opened database successfully: " << C.dbname() << endl;
      } 
 else {
       cout << "Can't open database" << endl;
         return 1;

      C.disconnect ();
   } 

}

int main() {
  psqlconn(); // call the function
  return 0; 
}

You declared and defined your function as void psqlconn(), the "void" signifying that it returned nothing.

Then you allowed it (in principle) to return 1;
thank you
