Thanks for sending that as a separate patch. As a matter of fact, I have already looked at what you are proposing here for the sake of the other thread when checking the difference in numbers with PQsendSyncMessage(). The logic looks sound, but I have a comment about the docs: could it be better to group \syncpipeline with \startpipeline and \endpipeline? \syncpipeline requires a pipeline to work. -- Michael
