The current functionality could be useful inside particular code paths
of an application, where you want to increase the log verbosity in a
particular part of the code, when it (unpredictably) happens, without
nuking the logs entirely.
Of course you are superuser when you review such logs, but I wouldn't
usually want the db connection from the application to have to run as
superuser if I could help it... especially not a web application.
