This is my first attempt at using libpq, and I'm running across a strange
problem. Here is my bare-bones program:
#include
#include "libpq-fe.h"
int main(int argc, char **argv) {
PGconn *conn;
fprintf(stderr, "connecting\n");
conn = PQconnectdb("dbname=postgres");
PQfinish(conn);

Yes, I used the same compilation command line for both versions:
gcc -o pq_test -I"C:\Program Files\PostgreSQL\8.3\include" -L"

Aha! This tip has led to the solution. I had been running the program from
an emacs shell buffer. If I run it from the Windows console or by

gcc won't give many warnings unless you give it a -Wall flag; it may be

Thanks, but both produce the same behavior as fprintf(stderr, "Connection \n"):
It prints when the PQconnectdb and PQfinish lines are commented out but not
