* ProcessNotifyInterrupt * * This is called if we see notifyInterruptPending set, just before * transmitting ReadyForQuery at the end of a frontend command, and * also if a notify signal occurs while reading from the frontend. * HandleNotifyInterrupt() will cause the read to be interrupted * via the process's latch, and this routine will get called. * If we are truly idle (ie, *not* i
