pg_cron partly jobs not running without any logs on job_run_details table.

PostgreSQL version is 11.5.
pg_cron 1.4-1.
OS: Centos 7.9

There are 50 jobs running by pg_cron. But 13 jobs stop unexpected since 2023 01/29.
This table cron.job_run_details also no infomation about those 13 failed jobs.
create new jobs also not running. others old jobs running normally.
This parameter is max_worker_processes=16.

Usually 1-3 jobs running in parallel.

Would you like to guide me resovle this issue ? How to collect infomation to narrow down it.

I don't find any upgrade method to update pg_cron.

How to upgrade pg_cron to new version without impact current jobs ? I mean don't need re-create all jobs. Thanks in advance.

Start with the reported pg_cron 1.4-1 behavior on PostgreSQL 11.5, focusing on cron.job_run_details and the max_worker_processes=16 setting. Reproduce or narrow down why some existing and newly created jobs do not run, and document diagnostic evidence and a safe upgrade path that preserves current jobs.
