So, translating it to a simpler example:

    You want that your function gets the connection ID it is using and
    ties it to your current user ID at your application and then have
    all your tables use a trigger to retrieve the user name from the
    auxiliar table that maps "connection ID -> user", right?

That's what's in that page: a UDF (user defined function) named
getapplicationid() that will return the user login / name / whatever and
triggers.

What is preventing you from writing that?  What is your doubt with
regards to how create that feature on your database?
