We (my company) never found a way. We ended up writing java code that
analyzed the catalog tables that generated the appropriate 'if'
statements in the trigger functions for us....

Inside our application, when we grab a connection from our connection
pool, the user information is populated into a termporary table that the
audit triggers can then later read for any transactions on that
connection.
