Yes, because in this case "0" doesn't mean "the result will be in
text", it means, "you issued the statement-variant of Describe, so I'm
not sure what the result format will be yet."
> If I asked for odd columns in text, even in binary do I need to choose proper format basing only on my request?
I don't quite understand this question, but I think so. I don't think
there's ever a situation where the server will ignore your result
format requests.

I wasn't able to reproduce that with my standalone test case. When I
changed the parameter oid to 23, I still got the same behavior. Can
you alter my test case to reproduce the error?
