My question is in the title Is it possible to use LISTEN / NOTIFY with the node node-red-contrib-postgresql (node) - Node-RED ?
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 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 with node-red-contrib-postgresql (node) - Node-RED and it works...
