Thread: Connected user in a triggerfunction

Connected user in a triggerfunction

Hi list,

We are using logging in a database based on triggers and plpgsql functions.
This works OK. However, we want deletes to be recorded too, and there we want
the user who connected to be recorded in the log. So, how can I get the
connected user in a triggerfunction?

Cheers,
Dick Kniep

Use SESSION_USER or CURRENT_USER.  They're usually the same but see
the documentation for how they can differ:

I thought I saw an answer to this yesterday. Have you tried CURRENT_USER
? It's in the "functions and operators" section of the manuals (contrary
to appearance, it is a function).
