Re: connecting using libpq breaks printf

This is my first attempt at using libpq, and I'm running across a strange
problem. Here is my bare-bones program:

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

int main(int argc, char **argv) {
 PGconn *conn;
 fprintf(stderr, "connecting\n");
 conn = PQconnectdb("dbname=postgres");
 PQfinish(conn);
 return 0;
}
