No; one circular buffer, period. Each backend would also internally buffer notifies that it hadn't yet delivered to its client --- but since the time until delivery could vary drastically across clients, I think that's reasonable. I'd expect clients that are using LISTEN to avoid doing long-running transactions, so under normal circumstances the internal buffer should not grow very large. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
