Thanks for your reply. To give more context: I am contributing to a Postgres driver used by a programming language. We are currently trying to understand what is legal/not legal to be sent through this connection. 

In the documentation it states that the simple query protocol is followed on these connections, which is why we assumed a multi-command statement would work. I just wanted to make sure we are not doing anything wrong and that it is disallowed by design. We can, for instance, send "SELECT 1;" and receive a result.


Please don't top-post.  The convention on these lists is to inline post.

If you are interacting at the protocol layer you probably should be posting to -hackers, not -novice.


Or a -bug report.  It would be good to show the code you are using to provoke the error.  But I do see where we document the Simple Query Protocol and do not qualify it such that it doesn't take a multi-command message.

Thank you. I will give those lists a shot. Apologies for the top-posting. I think I did it properly this time but gmail is a bit weird. Apologies if this is not inline either.
