這個真正的 JSONB 列

我找不到任何關于如何處理這種 JSONB 的例子

無論插入您的資料是什么都搞砸了。它采用 JSON 物件的字串表示并將其填充到 JSON 字串標量中。你需要解決這個問題,否則它會繼續發生。
要修復已經存在的內容,您需要從 JSON 字串中提取真正的 PostgreSQL 字串,然后將其轉換為 JSONB。使用 提取 JSON 字串可能不直觀#>>'{}',甚至不直觀->>0。
select (data#>>'{}')::jsonb from table_name.
當然,您應該永久修復它,而不是一直在運行中進行,這既緩慢又令人困惑。
update table_name set data=(data#>>'{}')::jsonb;
當然,修復首先搞砸的工具,修復歷史資料,需要以協調的方式完成,否則你的手上會一團糟。

我認為您在 jsonb 欄位中的格式字串錯誤。您可以嘗試通過以下方式修復它:
select trim(both '"' from replace(data::varchar, '\"', '"'))::jsonb data from tbl;
