log_min_messages = warning

We recently upgraded from postgres 12.8 to 14.3.  We are running Aurora Postgres on AWS.

We have procedures that will make calls to RAISE NOTICE to write out messages if you interactively call the procedure through psql.  These procedures are getting called by pg_cron.

Since upgrading these RAISE NOTICE messages are getting written to the postgres log file:

For example:

13:45:00.720882-05

CONTEXT: PL/pgSQL function perf.snap_stats() line 242 at RAISE

2022-09-06 18:45:01 UTC::@:[21535]:LOG: cron job 2: NOTICE: Snapping dba_hist_system_event at 2022-09-06 13:45:00.725818-05

Log_min_messages is set to warning so my understanding is that should only log messages at warning, error, log, fatal, or panic.  Any idea how to troubleshoot why these are getting written to the log file?

Thanks
