我有一个 Postgres 物化视图：
Column | Type | Modifiers
---------------------+-------------------+-----------
document_id | character varying |
recorded_date | date |
parcels | jsonb |
Indexes:
"index_my_view_on_document_id" btree (document_id)
"index_my_view_on_recorded_date" btree (recorded_date)
"index_my_view_on_parcels" gin (parcels)
我正在尝试执行一个分页查询，该查询在parcelsjsonb 数组字段上进行过滤，但是每当我添加 LIMIT 时，我的性能就会下降：
无限制：
EXPLAIN ANALYZE SELECT document_id FROM my_view WHERE (parcels @> '[3022890014]') ORDER BY recorded_date DESC;
