Thank you, Sir!
It is, indeed, a good idea!

Hello!
I need a feature that would me allow to debug "live" the work of an application together with a PostgreSQL database.
I think that if I would be able to define a session variable that is visible in pg_stat_activity (or in other system view, table or function) I would be more than happy.
Well, I have described what I see as a partial solution to my problem, the problem being: how to track a specific set of actions at database level of a given application user in the context of session pooling (so the user activity can jump from one session to another of the same pool).
If I would be able to set a "value" to a custom variable, then the app would simply need to set the value at each session usage, but I definitely understand that other mechanisms might help solving the problem (but I do not know any of these).
I had been trying something similar to play with tracing. I was wondering if the traceid or requestid could make its way into the query logs to be able to debug.The only thing I could find was play around with param application_name that could be set for each session with the traceid of my downstream and enable logging to log application name via log_line_prefix.
I'll be interested to know as well if there are any other parameters.
