I seem to remember that when it was first implemented there was a fairly small buffer for queued messages. That might have contributed to your problem. The docs say it's 8GB by default now, which is probably sufficient.
- williamstein 10y agoMessages are limited to 8KB, so if the buffer is 8GB, that's a lot of messages that can be queued up.
- masklinn 10y agoThe original NOTIFY also didn't have a payload (that was added in PG9) which made it much harder to know what you were notified about. That one simple addition made pre-9.0 NOTIFY and post-9.0 NOTIFY completely different beasts.
