We made some performance improvements for NOTIFY just a couple months ago, cf commits b10f40bf0, bb5ae8f6c, bca6e6435, 51004c717. It would be interesting to know how much those changes helped your use-case. I'm quite disinclined to reduce the correctness guarantees around NOTIFY for performance's sake. That's the sort of thing that sounds like a good idea until you find out that it subtly breaks your application, and then you've got nothing. regards, tom lane
