By the time you need append-only job statuses it's better to move to a dedicated queue. Append-only statuses help but they also make the polling query a lot more expensive.
Deleting older rows is a nightmare at scale. It leaves holes in the earlier parts of the table and nerfs half the advantage of using append-only in the first place. You end up paying 8kb page IO costs for a single job.
Dedicated queues have constant time operations for enqueue and dequeue which don't blow up at random times.
It's far from trivial. Autoanalyze doesn't work on partitioned tables, only on the partitions themselves. Partitioning a busy job queue table is a nightmare in itself.
