I have tried many postgres node but I can't find any node that's working.

I have a flow example here:

```auto

I've seen this code in other forum solution and when I tried. It's not working on my side. Do you have sample postgres node that I can try?

what exactly is not working?

Does it connect? Does it error when you inject data? What error? Can you query and insert DATA using another application?

the flow above is not saving in my database. And the flow below is my recent updates but also not saving to my database. I have tried the query using query tool in my postgres and it's working
