My question is in the title 🙂 Is it possible to use [LISTEN / NOTIFY](https://www.postgresql.org/docs/current/sql-listen.html) with the node [node-red-contrib-postgresql (node) - Node-RED](https://flows.nodered.org/node/node-red-contrib-postgresql) ?  
I've tried it but it does not work...

I'm not a consumer of `postgresql` - so not sure what that means.

But you might have answered your own question, if its not supported, you will need to request this as a feature with the author.

I think you are true, there is a PR : [Pull requests · alexandrainst/node-red-contrib-postgresql · GitHub](https://github.com/alexandrainst/node-red-contrib-postgresql/pulls) that is not merged...

I reply to myself to share the solution i've found.  
I use the nodes [node-red-contrib-postgrestor-next (node) - Node-RED](https://flows.nodered.org/node/node-red-contrib-postgrestor-next) with [node-red-contrib-postgresql (node) - Node-RED](https://flows.nodered.org/node/node-red-contrib-postgresql) and it works...
