Except the OP shows a command that is not in the above, authentication.

Also this:

https://www.postgresql.org/docs/11/event-trigger-interface.html

The command tag associated with the event for which the event trigger is
run, for example "CREATE FUNCTION".

I suspect it comes from the commands listed here:

/src/include/commands
/src/backend/commands

How to pull out the complete list is beyond me at the moment.

That's actually the "activity" portion of the process status display,
which there's no formal specification for. You'd have to root around
in the source code looking for set_ps_display() calls if you really
want to know.
