Description:        Can't get right type oid  by PQftype.
Details: 

I create a domain type testdomainoid.

CREATE DOMAIN testdomainoid int  CHECK(value >20);

In my database,the type oid of testdomainoid is 16385.But PQftype return 23
for testdomainoid's type oid.How could I get the testdomainoid's type oid.

--Creating a table use domain type.
CREATE TABLE test_domain_oid ( col testdomainoid );

--Insert a value.
INSERT INTO test_domain_oid VALUES (30);

//following is my test code.
#include <iostream>
#include "libpq-fe.h"
#include <sstream>

int main(int argc, char ** argv){
        PGconn * conn = PQconnectdb("");
        if( CONNECTION_OK != PQstatus(conn ) )
        {
                std::cout << "\nCan't connecte to db\n";
                return 0;
        }

        PGresult * r = PQexec( conn, "SELECT col FROM test_domain_oid " );
        if( PGRES_TUPLES_OK == PQresultStatus(r) )
        {
                Oid id = PQftype( r, 0 );
                int mod = PQfmod( r, 0 );
                std::cout<<"\noid: " << id<<"\nmod:" << mod <<std::endl;
        }
        else
        {
                std::cout << "\nQuery failed..\n";
                return 0;
        }

        PQclear( r );
        PQfinish( conn );
};
