Huh? The entire point of listen/notify is exactly that you don't have to poll.

- fauigerzigerk 12y agoAnd yet in previous versions of libpq polling was the only way to use listen/notify. I'm not sure if it was a limitation of libpq or the server implementation itself: http://www.postgresql.org/docs/9.4/static/libpq-notify.html http://www.postgresql.org/docs/9.4/static/libpq-notify.html It's still not a particularly simple interface as you have to check for notifications after every single SQL command if I understand it correctly.
