Custom "return message"

Is it possible to set a custom return message in a function or a procedure that would then show up in the job_run_details table?

Start by examining how pg_cron executes functions and procedures and how results are recorded in the job_run_details table. Determine whether a custom return message should apply to functions, procedures, or both, and define the expected stored value and behavior before identifying implementation and test locations.
