The code is pretty basic, in my opinion. The following is the snippet that's
failling. By the time execution gets to this point, the connection is open,
and the first line always prints 0 1 0
---cout<<conn<<": "<<PQstatus( conn )<<" "<<CONNECTION_BAD<<"
"<<CONNECTION_OK<<endl;PGresult * result=PQexec( conn, "BEGIN" );cout<<"here a"<<endl;PQclear( result );
cout<<"here a.1"<<endl;result=PQexec( conn, stmt );cout<<"here a.2"<<endl;

If you aren't getting answers it's not because nobody looked at this. I
did, and I can't figure it out. You are apparently running 7.3.x based on 
Same here..:-)

 I had a thought  yesterday but didn't put it because was not sure how helpful it is... anyways..

Are your postgresql include headers are within a extern "C" block? In C++, that can cause quite a grief. Check it out..
