postgresql RAISE 消息是否存储在某处?

Are postgresql RAISE messages stored somewhere?

具体来说,我想看看我是否可以检索我用来在控​​制台中查看进度的 RAISE INFO 消息。

这些存储在 pg 中的某个地方吗?

Not necessarily:

Whether messages of a particular priority are reported to the client, written to the server log, or both is controlled by the log_min_messages and client_min_messages configuration variables.
