How to log pg_terminate_backend() calls

We see some "FATAL: terminating connection due to administrator command" error messages in the Postgres logfile.
We assume someone did pg_terminate_backend() calls.
How can we log such calls, especially who did the call?

There's no built-in facility for that, short of log_statement = all.

You could try making a wrapper function: rename pg_terminate_backend
to something else and then make a plpgsql equivalent that issues
RAISE LOG and then calls the renamed function.
