There's no reason that the buffer size we use for XLogRead() should be the same as the send buffer, if you're worried about that. My point is that pq_putmessage contains internal flushes so at the libpq level you gain nothing by big batches. The read() will be buffered anyway with readahead so not sure what the issue is. We'll have to do this for sync rep anyway, so what's the big deal? Just do it now, once. Do we really want 9.1 code to differ here?
