Or simply INSERT, UPDATE, DELETE, SELECT, MOVE, FETCH and/or COPY

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.

    CommandComplete (B), string value of this section.

    I loaded log file (csv format) into postgres_log table as per below
    document and can see entries like:
    https://www.postgresql.org/docs/10/runtime-config-logging.html

    postgres=# select command_tag from postgres_log where command_tag is
    not null limit 5;
       command_tag

    Can you show example of a command tag in the log?
