Alex Vandiver 6e91e326e9 deferred_work: Reduce batch size due to bad statistics. ... PostgreSQL's estimate of the number of usermessage rows for a single message can be wildly off, due to poor statistics generation. This causes this query, with 100-message batch sizes, to incorrectly estimate millions of matched rows, causing it to perform a full-table index scan, rather than piecemeal using the `message_id` index. Reduce the batch size to 50, which is enough to tip in favor of a rational query plan.		2024-03-11 09:24:59 -07:00
