Is it possible to write a generic trigger for all tables in Postgres?

Question

I want to listen to every transaction that is recorded in the database And I noticed that there is a concept in Postgres under the title LISTEN and NOTIFY (Of course, I am not sure that this is the right way)

Now I want to write a trigger that sends a notification to the channel when any operation occurs in any table

Is it possible?

My way is right?

thanks
