Really? I tried it and got 172069, which is about right for where the
OID counter is in my database. I think you messed up your test.
res = PQexec(conn, "select * from my_varchar_test");
if (PQresultStatus(res) != PGRES_TUPLES_OK)
{
fprintf(stderr, "SELECT failed: %s", PQerrorMessage(conn));
PQclear(res);
exit_nicely(conn);
}
nFields = PQnfields(res);
for (i = 0; i < nFields; i++)
printf("%-15s %d\n", PQfname(res, i), PQftype(res, i));
