That's messy. I'd recommend getting out a debugger and tracing through
it to see exactly where it's failing. Or put in some printf's. There
aren't that many paths that could return NULL. I guess one of them must
be forgetting to set PQerrorMessage, which seems like a bug to me. Let
us know what you find out.
