Не могу подключиться к базе данных PostgreSQL

При компиляции есть всегда ошибка 0xc0150002. Может кто-то может помочь?

#include <string>
#include "libpq-fe.h"


/* Close connection to database */
void CloseConn(PGconn* conn)
{
    PQfinish(conn);
    getchar();
    exit(1);
}
/* Establish connection to database */
PGconn* ConnectDB()
{
    PGconn* conn = NULL;
    conn = PQconnectdb("user=postgres password=test123 dbname=testdb hostaddr=127.0.0.1 port=5432");

    // Check to see that the backend connection was successfully made
    if (PQstatus(conn) != CONNECTION_OK)
    {
        printf("Connection to database failed");
        CloseConn(conn);
    }

    printf("Connection to database - OK\n");

    return conn;
}



int main() {
    return 0;
}
