Per here:

https://www.postgresql.org/docs/current/plpgsql-errors-and-messages.html#PLPGSQL-STATEMENTS-RAISE

"Whether messages of a particular priority are reported to the client, 
written to the server log, or both is controlled by the log_min_messages 
and client_min_messages configuration variables. See Chapter 20 for more 
information."

I have not tried it but maybe SET client_min_messages to something above 
NOTICE in the function.

Or as part of the function creation:

https://www.postgresql.org/docs/current/sql-createfunction.html

SET configuration_parameter { TO value | = value | FROM CURRENT }
